* Shapes can be draw using 3 types of primitives: LINES, TRIANGLES and QUADS.

* Some functions define texture coordinates (rlTexCoord2f()) for the shapes and use a
* user-provided texture with SetShapesTexture(), the pourpouse of this implementation
* is allowing to reduce draw calls when combined with a texture-atlas.
*
* By default, raylib sets the default texture and rectangle at InitWindow()[rcore] to one
* By default, raylib sets the default texture and rectangle at InitWindow()[rcore] to one
* white character of default font [rtext], this way, raylib text and shapes can be draw with
* a single draw call and it also allows users to configure it the same way with their own fonts.
*
* CONFIGURATION:
*
* #define SUPPORT_MODULE_RSHAPES
* rshapes module is included in the build
*
* #define SUPPORT_QUADS_DRAW_MODE
* Use QUADS instead of TRIANGLES for drawing when possible. Lines-based shapes still use LINES
