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.

* Added Box and Gaussian blurring

* Removed dependence of gaussian blur to box blur & Fixed precision errors

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

- ADDED: `GetCodepointPrevious()`
 - RENAMED: `GetCodepoint()` -> `GetCodepointNext()`, actually, reimplemented
 - `GetCodepoint()` has been kept for the moment, for compatibility and also because implementation is different
 - RENAMED: `TextCodepointsToUTF8()` to `LoadUTF8()`, simpler name and more aligned with raylib conventions (functions loading memory start with Load*()), parameters should be descriptive of functionailty.
 - ADDED: `UnloadUTF8()`, aligned with `LoadUTF8()` to avoid allocators issues.

This adds `ImageDrawCircleLines()` and `ImageDrawCircleLinesV()` to draw outlines of circles, and updates `ImageDrawCircle()` draw a filled circle to match the effect of `DrawCircle()` and `DrawCircleLines()`.

* Update raylib.h

* CheckCollisionPointPolygon()

* typo

* Fix Undefined Symbol `_ftelli64`

* Add files via upload

* Update raylib.h

* Update raylib.h

Those functions were platform dependent and user has no control over the file created. They have been removed from raylib and just moved to `core_storage_values` example.

(GetMouseWheelMoveV).

REDESIGNED: `LoadDirectoryFiles()`
ADDED: `LoadDirectoryFilesEx()`
REDESIGNED: `LoadDroppedFiles()`
ADDED: `IsPathFile()`

This BIG BREAKING change simplifies the functions and gives more control to the user:
 - A new `struct FilePathList` has been added to avoid exposing complex pointers.
 - User is responsible of memory loading/unloading
 - Filepaths loading support recursive directories and file extension filters

* GetMonitorWidth()/GetMonitorHeight(): current video resolution instead max available

* adapt header comment to reflect change

RENAMED: `ClearDroppedFiles()` to `UnloadDroppedFiles()`

RENAMED: `ClearDirectoryFiles()` to `UnloadDirectoryFiles()`

Events waiting can be enabled/disabled, it toggles event polling.

When referring to byte array SIZE, I find it more clear than length

This feature is still under consideration/testing and it doesn't work properly, at least the Delay Effect processor.
