- DrawTextRec() and DrawTextRecEx() have been moved to example, those functions could be very specific depending on user needs so it's better to give the user the full source in case of special requirements instead of allowing a function with +10 input parameters.

* Fix Makefile to build WASM examples.

- Add --preload-file flag before specifying the resource dir
- Add empty resource dir to `shapes/` (otherwise wasm-ld will fail)
- Add wasm outputs to .gitigore

* Delete .gitignore

Now rlgl uses the `Matrix` type, just make sure it has been previously defined somewhere... I don't like this approach but it's probably the easier one for the users... still looking for a better solution... maybe using something like
`#define MATRIX_TYPE`, so it can be checked in other modules.

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

Simplified the example

This design should probably be changed...

RENAMED: GetTextureData() -> LoadImageFromTexture()
RENAMED: GetScreenData() -> LoadImageFromScreen()

Some functions/values have been deprecated for long time but some mapping was kept for convenience. Some of those mappings have been removed...

* Added my own model and license to Raylib exclusively created by me and provided for use in the examples (and other projects if anyone decides to)

* Use animation vertices on initial load if possible.

* Added girl model to model example

* Revamped GLTF model loading as it was wrong by default. Also updated some comments.

GLTF models were loaded only by mesh but they should be loaded recursively by hierarchical nodes because tehre are some static node transformations that are to be applied to the vertices. It also resulted in more meshes being included in some models.

It is the correct way of loading GLTF and what is suggested in the official examples.

Currenlty limiting to only one scene but more can be included later.

* Refactored the new names and structure of extracted functions.

* Safer and easier read value.

* Made reading easier for accessor->bufferView->buffer in GLTF.

Now there is no need to check for supported types or anything.

* Correct inclusion of limits.h in the cases of MSVC based compilers vs the world

* Removed weird example file

When a shader is loaded, by default, several locations are tried to be set automatically.

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()

Moved outside BeginDrawing()/EndDrawing() to illustrate drawing is happening to an external texture (not screen)

Added missing null terminator when adding characters to the string, otherwise garbage values are read (often zeros which are equal to '\0', but not every time).

This error results in random characters appearing in the text box every one in a while:
```
asdfg??? ll??
```
It is corrected with the proposed fix.

This problem was observed by my student, Gonzalo Rivera Lazo.

RENAMED: InitAudioStream() -> LoadAudioStream()
RENAMED: CloseAudioStream() -> UnloadAudioStream()

* review collisions ray-box and ray-sphere

* Applied raysan's refactor
Improved GetRayCollisionBox

* Replace GetRayCollisionGround with GetCollisionQuad

* Update example core_3d_picking

* Update example models_loading

* Fixed issues after merge

* remove debug stuff
