Reviewed formating to follow raylib coding conventions.

rlCullFace sets the face culling mode to RL_FRONT or RL_BACK which correspond to GL_FRONT and GL_BACK respectively.

Added a comment explaining the range limitations of GetRandomValue.
Added a run-time warning TRACELOG when GetRandomValue is called with an invalid range.

Those two functions have been moved to a new example: `models_draw_cube_texture`. The reasons for this decision:
 - Function inflexibility: Many users with the need to draw a textured cube could need to customize the texture applied to every face, that function did not allow that kind of functionality.
 - rlgl functionality exposure: The implementation exposed will teach users how to implement custom textured triangles drawing.

This function implementation has been moved to the related example. Current implementation can be probably customized depending on user needs.

This function can be easely replicated using `DrawtexturePro()` and actually it was doing some assumptions not transparent to the user. Even the function name was confusing. No example was available for it and actually noone requested one example.

Function moved to `examples/textures/textures_polygon.c`, so users can learn from the implementation and create custom variants as required.

* build.zig: let user decide how to set build mode

This should delegate the responsibility of calling `standardReleaseOptions` and setting the build mode of the `*LibExeObjStep` step to the caller, especially since this might not be the process by which one wants to determine the build mode.

Also changes hides `getSrcDir` to enforce usage of `srcdir`, and asserts that the file is in fact inside a directory.

* build.zig: set root_src param to `null`

Supplying the header file as the root source here appears to cause a linker warning of the form:
```
LLD Link... warning(link): unexpected LLD stderr:
ld.lld: warning: {build_root}/zig-cache/o/{hash}/libraylib.a: archive member '{build_root}/zig-cache/o/{hash}/raylib.o' is neither ET_REL nor LLVM bitcode
```
Passing `null` instead fixes it.

* Use RL_QUADS/RL_TRIANGLES for single-pixel drawing

Addresses problem mentioned in

(in short: when drawing pixels using DrawPixel{,V} in camera mode,
upscaled pixel becomes a line instead of bigger pixel)

* [rtextures] Fixed scaling down in ImageTextEx

Closes #2755

Probably useless but interesting for education. It generated a grayscale image directly from text data.

and make version check be only 150 not over 150

Fix for #2714

* removed glfwSetWindowPos on InitWindow

* removed execute permission from CMakeLists

* fix issue #2728

* updated gamecontrollerdb: fixes GLFW warning due to invalid entry

zig `master` now enforces to use addIncludePath instead of addIncludeDir
