* [rcore] fix rpi4 Failed to get DRM resources

card1 is not always the the correct card to use on rpi4
rpi os finds the correct card and links it to /dev/dri/by-path/platform-gpu-card during boot.
this fix makes sure that we always point to the correct card on rpi4

* Update rcore.c

Still, it depends on Matrix type... rcamera module should be completely reviewed...

* Supress most warnings on rmodels.c

NOTE: unused symbols have been deleted and the following report will show in what location they were previously.

Unused symbols:
- ArrayInt - vox_loader.h: line 84
- initArrayInt - vox_loader.h: line 168
- insertArrayInt - vox_loader.h: line 175
- freeArrayInt - vox_loader.h: line 186
- offsetX, offsetY, offsetZ - vox_loader.h: line 610
- chunkTotalChildSize - vox_loader.h: line 623

Other warnings:
- initialization discards 'const' qualifier - vox_loader.h: line 572
- incompatible types for VoxVector3 and Vector3 - rmodels.c: line 5748
- incompatible types for VoxColor and Color - rmodels: line 5749

* Remove ToVector3 and ToColor functions and assign values directly

CONVENTIONS:
  - Functions are always self-contained, no function use another raymath function inside, required code is directly re-implemented inside
  - Functions input parameters are always received by value
  - Functions use always a "result" variable for return
  - Functions are always defined inline
  - Angles are always in radians (DEG2RAD/RAD2DEG macros provided for convenience)

The build file builds Raylib as a static library for either
Windows or Linux.

* Fixed gltf missing transforms on load

mend

* extracted Matrix calculation in to static method and added skinning check

* fixed formatting

* Fixed write to access to nullptr when animation has no normals

* Refactored UpdateModelAnimation to only update changed vertices when needed (allows for multi animation playing)

* add check for models that were missed during BindGLTFPrimitiveToBones to not segfault the program

* fixed id mismatch between animation and model

* draft on fixing the mesh to skin mapping

* dont look at this

* removing debug info

'# TODO: see 'install' target.' should be a note rather than something
to do.

* Add function DrawCubeTextureRec

* Add EOF newline

* Remove unneeded example

LoadModelAnimations takes an `int` for the animation count parameter.
The animation count should never be negative, so it makes sense to
specify it as unsigned in the API. This matches the API for
UnloadModelAnimations, which expects an unsigned int. Both GLTF and IQMM
also store the animation count internally as unsigned, and we were
casting to a signed int for no reason.

GLTF actually uses `size_t` internally, so we're technically risking
overflow, but having 2^32 animations seems unlikely.

raylib modules have been slightly renamed to add some identity and note that they are independent modules that can be used as standalone separate parts of raylib if required.

The renamed modules are:
 - `core` -> `rcore`
 - `shapes` -> `rshapes`
 - `textures` -> `rtextures`
 - `text` -> `rtext`
 - `models` -> `rmodels`
 - `camera` -> `rcamera`
 - `gestures` -> `rgestures`
 - `core` -> `rcore`

All the build systems has been adapted to this change.

* Add `up` argument to `DrawBillboardPro`

* Replace tab with proper spaces

- Ran GenerateMappings.cmake to restore mapping changes

Specifying a fixed seed for the random number generator is often
used in games for various reasons.

By adding an api function for seeding the random number generator
we solve two different problems regarding the seeding:

1) The underlying RNG implementation does not leak to client code
   (as would be the case if we called srand directly from the
   client code)
2) Seeding the RNG would be simple from other programming languages
   (especially in cases where calling libc functions is non-trivial)

i got an error because of this lol

* implemented GetGamepadName for emscripten

* updated gamepad to use existing name as arary

* removed unnecessary platform_web check

Some flags are only for the linker, not the compiler

* new models_magicavoxel_loading example

* Portable header-only file "magicavoxel_loader.h" for MagicaVoxel loader example.

* models_magicavoxel_loading example added to CMakeLists.txt and Makefile

* fix models_magicavoxel_loading example for linux.

* * vox_loader into "src/external/vox_loader.h"
 * vox file support for "models.c"
 * updated example "models/models_magicavoxel_loading.c"

* * Fix Vox_FreeArrays (removed memory leak)

* * removed magicavoxel_loader.h

* * Revert vs2019 solution

* * vox_loader.h -> Support custom memory allocators
* vox_loader.h -> Reverse Y<>Z for left to right handed system
* models/models_magicavoxel_loading.c -> fix model center

* * vox_loader.h -> Removed Raylib dependencies

* * Changed Vox_LoadFileName to Vox_LoadFromMemory

- ADDED: `GetTouchPointCount()` to core module, removed from gestures module.
 - Support multiple touch points: `MAX_TOUCH_POINTS`.
