ConvertToGLformat ( PixelBox data, OpenTK.Graphics.ES11 &outputFormat ) : PixelBox

GetClosestAxiomFormat ( OpenTK.Graphics.ES11 fmt ) : PixelFormat

Function to get the closest matching Axiom format to an internal GL format. To be precise, the format will be chosen that is most efficient to transfer to the card without losing precision. It is valid for this function to always return PixelFormat.A8R8G8B8.
GetClosestGLInternalFormat ( PixelFormat mFormat, bool hwGamma = false ) : OpenTK.Graphics.ES11.All

Takes the Axiom pixel format and returns the type that must be provided to GL as internal format. If no match exists, returns the closest match.
GetGLInternalFormat ( PixelFormat fmt, bool hwGamma ) : OpenTK.Graphics.ES11.All

Takes the Axiom pixel format and returns the type that must be provided to GL as internal format. 0 if no match exists.
GetGLOriginDataType ( PixelFormat mFormat ) : OpenTK.Graphics.ES11.All

Takes the Axiom pixel format and returns type that must be provided to GL as data type for reading it into the GPU
GetGLOriginFormat ( PixelFormat fmt ) : OpenTK.Graphics.ES11.All

Takes the Axiom pixel format and returns the appropriate GL one
GetMaxMipmaps ( int width, int height, int depth, PixelFormat format ) : int

Returns the maximum number of Mipmaps that can be generated until we reach the mininum format possible. This does not count the base level.

In case that the format is non-compressed, this simply returns how many times we can divide this texture in 2 until we reach 1x1. For compressed formats, constraints apply on minimum size and alignment so this might differ.

OptionalPO2 ( int value ) : int

Returns next power-of-two size if required by render system, in case RSC_NON_POWER_OF_2_TEXTURES is supported it returns value as-is.
