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

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

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()`.

raylib was using `stb_perlin.h` library to generate perlin noise, it seems that recently this library has been flagged as it could be infringing some algorythm patent. For security, it has been removed from raylib.

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)

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 support for additional mouse buttons

* Renamed mouse button enum

* 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" )

* Fix some warnings in examples.

* cleanups from review

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

RENAMED: CubemapLayoutType and NPatchType

* Fixing typecast warnings generated by visual studio 2019 in examples.

* Changes to fixes based on feedback

This function was renamed for consistency in raylib 3.0, just unified all examples to use TextFormat() instead of FormatText()

* Implemented DrawTextureTiled()

* Example added
