+// FAQ
+//
+// Q: What counts as a tilemap for this library?
+//
+// A: An array of rectangles, where each rectangle contains a small
+// stack of images.
+//
+// Q: What are the limitations?
+//
+// A: Maps are limited to 4096x4096 in dimension.
+// Each map square can only contain a stack of at most 32 images.
+// A map can only use up to 32768 distinct image tiles.
+//
+// Q: How do I compile this?
+//
+// A: You need to #define several symbols before #including it, but only
+// in one file. This will cause all the function definitions to be
+// generated in that file. See the "HOW TO COMPILE" section.
+//
+// Q: What advantages does this have over a standalone editor?
+//
+// A: For one, you can integrate the editor into your game so you can
+// flip between editing and testing without even switching windows.
+// For another, you don't need an XML parser to get at the map data.
+//
+// Q: Can I live-edit my game maps?
+//
+// A: Not really, the editor keeps its own map representation.
+//
+// Q: How do I save and load maps?
+//
+// A: You have to do this yourself. The editor provides serialization
+// functions (get & set) for reading and writing the map it holds.
+// You can choose whatever format you want to store the map to on
+// disk; you just need to provide functions to convert. (For example,
+// I actually store the editor's map representation to disk basically
+// as-is; then I have a single function that converts from the editor
+// map representation to the game representation, which is used both
+// to go from editor-to-game and from loaded-map-to-game.)
+//
+// Q: I want to have tiles change appearance based on what's
+// adjacent, or other tile-display/substitution trickiness.
+//
+// A: You can do this when you convert from the editor's map
+// representation to the game representation, but there's
+// no way to show this live in the editor.
+//
+// Q: The editor appears to be put map location (0,0) at the top left?
+// I want to use a different coordinate system in my game (e.g. y
+// increasing upwards, or origin at the center).
+//
+// A: You can do this when you convert from the editor's map
+// representation to the game representation. (Don't forget to
+// translate link coordinates as well!)
+//
+// Q: The editor appears to put pixel (0,0) at the top left? I want
+// to use a different coordinate system in my game.
+//
+// A: The editor defines an "editor pixel coordinate system" with
+// (0,0) at the top left and requires you to display things in
+// that coordinate system. You can freely remap those coordinates
+// to anything you want on screen.
+//
+// Q: How do I scale the user interface?
+//
+// A: Since you do all the rendering, you can scale up all the rendering
+// calls that the library makes to you. If you do, (a) you need
+// to also scale up the mouse coordinates, and (b) you may want
+// to scale the map display back down so that you're only scaling
+// the UI and not everything. See the next question.
+//
+// Q: How do I scale the map display?
+//
+// A: Use stbte_set_spacing() to change the size that the map is displayed
+// at. Note that the "callbacks" to draw tiles are used for both drawing
+// the map and drawing the tile palette, so that callback may need to
+// draw at two different scales. You should choose the scales to match
+// You can tell them apart because the
+// tile palette gets NULL for the property pointer.
+//
+// Q: How does object editing work?
+//
+// A: One way to think of this is that in the editor, you're placing
+// spawners, not objects. Each spawner must be tile-aligned, because
+// it's only a tile editor. Each tile (stack of layers) gets
+// an associated set of properties, and it's up to you to
+// determine what properties should appear for a given tile,
+// based on e.g. the spawners that are in it.
+//
+// Q: How are properties themselves handled?
+//
+// A: All properties, regardless of UI behavior, are internally floats.
+// Each tile has an array of floats associated with it, which is
+// passed back to you when drawing the tiles so you can draw
+// objects appropriately modified by the properties.
+//
+// Q: What if I want to have two different objects/spawners in
+// one tile, both of which have their own properties?
+//
+// A: Make sure STBTE_MAX_PROPERTIES is large enough for the sum of
+// properties in both objects, and then you have to explicitly
+// map the property slot #s to the appropriate objects. They'll
+// still all appear in a single property panel; there's no way
+// to get multiple panels.
+//
+// Q: Can I do one-to-many linking?
+//
+// A: The library only supports one link per tile. However, you
+// can have multiple tiles all link to a single tile. So, you
+// can fake one-to-many linking by linking in the reverse
+// direction.
+//
+// Q: What if I have two objects in the same tile, and they each
+// need an independent link? Or I have two kinds of link associated
+// with a single object?
+//
+// A: There is no way to do this. (Unless you can reverse one link.)
+//
+// Q: How does cut & paste interact with object properties & links?
+//
+// A: Currently the library has no idea which properties or links
+// are associated with which layers of a tile. So currently, the
+// library will only copy properties & links if the layer panel
+// is set to allow all layers to be copied, OR if you set the
+// "props" in the layer panel to "always". Similarly, you can
+// set "props" to "none" so it will never copy.
+//
+// Q: What happens if the library gets a memory allocation failure
+// while I'm editing? Will I lose my work?
+//
+// A: The library allocates all editor memory when you create
+// the tilemap. It allocates a maximally-sized map and a
+// fixed-size undo buffer (and the fixed-size copy buffer
+// is static), and never allocates memory while it's running.
+// So it can't fail due to running out of memory.
+//
+// Q: What happens if the library crashes while I'm editing? Will
+// I lose my work?
+//
+// A: Yes. Save often.
+//
+//
+// HOW TO COMPILE
+//
+// This header file contains both the header file and the
+// implementation file in one. To create the implementation,
+// in one source file define a few symbols first and then
+// include this header:
+//
+// #define STB_TILEMAP_EDITOR_IMPLEMENTATION
+// // this triggers the implementation
+//
+// void STBTE_DRAW_RECT(int x0, int y0, int x1, int y1, uint color);
+// // this must draw a filled rectangle (exclusive on right/bottom)
+// // color = (r<<16)|(g<<8)|(b)
+//
+// void STBTE_DRAW_TILE(int x0, int y0,
+// unsigned short id, int highlight, float *data);
+// // this draws the tile image identified by 'id' in one of several
+// // highlight modes (see STBTE_drawmode_* in the header section);
+// // if 'data' is NULL, it's drawing the tile in the palette; if 'data'
+// // is not NULL, it's drawing a tile on the map, and that is the data
+// // associated with that map tile
+//
+// #include "stb_tilemap_editor.h"
+//
+// Optionally you can define the following functions before the include;
+// note these must be macros (but they can just call a function) so
+// this library can #ifdef to detect if you've defined them:
+//
+// #define STBTE_PROP_TYPE(int n, short *tiledata, float *params) ...
+// // Returns the type of the n'th property of a given tile, which
+// // controls how it is edited. Legal types are:
+// // 0 /* no editable property in this slot */
+// // STBTE_PROP_int /* uses a slider to adjust value */
+// // STBTE_PROP_float /* uses a weird multi-axis control */
+// // STBTE_PROP_bool /* uses a checkbox to change value */
+// // And you can bitwise-OR in the following flags:
+// // STBTE_PROP_disabled
+// // Note that all of these are stored as floats in the param array.
+// // The integer slider is limited in precision based on the space
+// // available on screen, so for wide-ranged integers you may want
+// // to use floats instead.
+// //
+// // Since the tiledata is passed to you, you can choose which property
+// // is bound to that slot based on that data.
+// //
+// // Changing the type of a parameter does not cause the underlying
+// // value to be clamped to the type min/max except when the tile is
+// // explicitly selected.
+//
+// #define STBTE_PROP_NAME(int n, short *tiledata, float *params) ...
+// // these return a string with the name for slot #n in the float
+// // property list for the tile.
+//
+// #define STBTE_PROP_MIN(int n, short *tiledata) ...your code here...
+// #define STBTE_PROP_MAX(int n, short *tiledata) ...your code here...
+// // These return the allowable range for the property values for
+// // the specified slot. It is never called for boolean types.
+//
+// #define STBTE_PROP_FLOAT_SCALE(int n, short *tiledata, float *params)
+// // This rescales the float control for a given property; by default
+// // left mouse drags add integers, right mouse drags adds fractions,
+// // but you can rescale this per-property.
+//
+// #define STBTE_FLOAT_CONTROL_GRANULARITY ... value ...
+// // This returns the number of pixels of mouse motion necessary
+// // to advance the object float control. Default is 4
+//
+// #define STBTE_ALLOW_LINK(short *src, float *src_data, \
+// short *dest, float *dest_data) ...your code...
+// // this returns true or false depending on whether you allow a link
+// // to be drawn from a tile 'src' to a tile 'dest'. if you don't
+// // define this, linking will not be supported
+//
+// #define STBTE_LINK_COLOR(short *src, float *src_data, \
+// short *dest, float *dest_data) ...your code...
+// // return a color encoded as a 24-bit unsigned integer in the
+// // form 0xRRGGBB. If you don't define this, default colors will
+// // be used.
+//
+//
+// [[ support for those below is not implemented yet ]]
+//
+// #define STBTE_HITTEST_TILE(x0,y0,id,mx,my) ...your code here...
+// // this returns true or false depending on whether the mouse
+// // pointer at mx,my is over (touching) a tile of type 'id'
+// // displayed at x0,y0. Normally stb_tilemap_editor just does
+// // this hittest based on the tile geometry, but if you have
+// // tiles whose images extend out of the tile, you'll need this.
+//
+// ADDITIONAL CONFIGURATION
+//
+// The following symbols set static limits which determine how much
+// memory will be allocated for the editor. You can override them
+// by making similiar definitions, but memory usage will increase.
+//
+// #define STBTE_MAX_TILEMAP_X 200 // max 4096
+// #define STBTE_MAX_TILEMAP_Y 200 // max 4096
+// #define STBTE_MAX_LAYERS 8 // max 32
+// #define STBTE_MAX_CATEGORIES 100
+// #define STBTE_UNDO_BUFFER_BYTES (1 << 24) // 16 MB
+// #define STBTE_MAX_COPY 90000 // e.g. 300x300
+// #define STBTE_MAX_PROPERTIES 10 // max properties per tile
+//
+// API
+//
+// Further documentation appears in the header-file section below.
+//
+// EDITING MULTIPLE LEVELS
+//
+// You can only have one active editor instance. To switch between multiple
+// levels, you can either store the levels in your own format and copy them
+// in and out of the editor format, or you can create multiple stbte_tilemap
+// objects and switch between them. The latter has the advantage that each
+// stbte_tilemap keeps its own undo state. (The clipboard is global, so
+// either approach allows cut&pasting between levels.)

+/////////////////////// undo system ////////////////////////
+
+// the undo system works by storing "commands" into a buffer, and
+// then playing back those commands. undo and redo have to store
+// the commands in different order.
+//
+// the commands are:
+//
+// 1) end_of_undo_record
+// -1:short
+//
+// 2) end_of_redo_record
+// -2:short
+//
+// 3) tile update
+// tile_id:short (-1..32767)
+// x_coord:short
+// y_coord:short
+// layer:short (0..31)
+//
+// 4) property update (also used for links)
+// value_hi:short
+// value_lo:short
+// y_coord:short
+// x_coord:short
+// property:short (256+prop#)
+//
+// Since we use a circular buffer, we might overwrite the undo storage.
+// To detect this, before playing back commands we scan back and see
+// if we see an end_of_undo_record before hitting the relevant boundary,
+// it's wholly contained.
+//
+// When we read back through, we see them in reverse order, so
+// we'll see the layer number or property number first
+//
+// To be clearer about the circular buffer, there are two cases:
+// 1. a single record is larger than the whole buffer.
+// this is caught because the end_of_undo_record will
+// get overwritten.
+// 2. multiple records written are larger than the whole
+// buffer, so some of them have been overwritten by
+// the later ones. this is handled by explicitly tracking
+// the undo length; we never try to parse the data that
+// got overwritten
+
+// given two points, compute the length between them
