* #define SUPPORT_GL_DETAILS_INFO

* #define SUPPORT_COMPUTE_SHADERS
* Enable compute shaders and shader storage buffer object support.
* Currently only work with GRAPHICS_API_OPENGL_33 with appropriate driver support.
*
* rlgl capabilities could be customized just defining some internal
* values before library inclusion (default values listed):
