rlgl has been redesigned to avoid any dependency to `raylib` or `raymath`, all functions using some of those libs have been reviewed.
- REMOVED: `Texture2D`, `Shader` structs dependency
- REMOVED: `Vector3`, `Matrix` structs dependency
- REMOVED: raymath functions dependency, all required math is implemented in rlgl
- ADDED: `rlMatrix` custom rlgl type
- ADDED: `utils.c`: `rlMatrixFromMatrix()` and `rlMatrixToMatrix()` for a safe conversion between raylib<->rlgl matrix types
- ADDED: `rl` prefix to all `rlgl` structs
- Other small tweaks here and there
* Implemented remaining 7/8 of ImageDrawLine
The existing code was correct for one octant, it now works for all 8
Added two internal functions, _ImageDrawLineHorizontal and _ImageDrawLineVertical, whithout which it would've been 4 times as much code.
* ImageDrawLine: Replaced 3 functions with 1
Removed both freshly added internal functions
Crammed it all into one
* ImageDrawLine shortened significantly using maths
Substituted X and Y, then wrote one abstract loop instead of 4 specific loops.
Lots of comments to explain what I'm doing for future maintainers.
* Now conforms with style conventions
Also reworded a comment to sound more... fomal.
RENAMED: GetCodepoints() -> LoadCodepoints(), now codepoint array data is loaded dynamically instead of reusing a limited static buffer.
ADDED: UnloadCodepoints() to safely free loaded codepoints
RENAMED: GetNextCodepoint() -> GetCodepoint()
* adds DrawTexturedPoly with example
* the actual example ... ahem
* moved DrawTexturePoly to textures function and example
NB function name changed to fit with other DrawTextureXXX functions
(no "d" )

- The vertices did not map to where I expected causing rotation to be
off by 90 degrees. I reorganized the vertices making it easier to
reason about which fixes this.
- The order for drawing is now topLeft, bottomLeft, bottomRight,
topRight.
- Many functions renamed to follow rl*() convention
- Some internal functions exposed in the API
- Some functionality moved to other modules
- Reorganized all functions by categories
- Make sure it keeps working with OpenGL 1.1 and 2.1
* Optimize DrawTexturePro and DrawRectanglePro transformations
- Add check so rotation is only applied if rotation != 0.0f.
- Replace matrix usage by calculating the vertex data directly.
* Fix error with windows build and trim whitespace
Some enums values have been renamed to be more consistent and also provide a more detailed description:
- ShaderLocationIndex: LOC_VERTEX_POSITION -> SHADER_SHADER_LOC_VERTEX_POSITION
- ShaderUniformDataType: UNIFORM_VEC2 -> SHADER_UNIFORM_VEC2
- MaterialMapType: MAP_ALBEDO -> MATERIAL_MAP_ALBEDO
- PixelFormat: UNCOMPRESSED_GRAYSCALE -> PIXELFORMAT_UNCOMPRESSED_GRAYSCALE
Pefixing/Suffixing some data type identifier in the variables is not a convention used in raylib, just reviewed it for consistency...
Still, I kept the *Rec suffix in some functions.
This is a BREAKING CHANGE!
To address the linked issue, several functions have been renamed and couterpart functions have been created to free loaded memory:
- RENAMED: GetImageData() -> LoadImageColors()
- RENAMED: GetImagePalette() -> LoadImagePalette()
- RENAMED: GetWaveData() -> LoadWaveSamples()
- ADDED: UnloadImageColors()
- ADDED: UnloadImagePalette()
- ADDED: UnloadWaveSamples()
