/**
* Native bindings to the ARB_texture_compression extension.
*
*
Compressing texture images can reduce texture memory utilization and improve performance when rendering textured primitives. This extension allows
* OpenGL applications to use compressed texture images by providing:
*
*
*
A framework upon which extensions providing specific compressed image formats can be built.
*
A set of generic compressed internal formats that allow applications to specify that texture images should be stored in compressed form without
* needing to code for specific compression formats.
*
*
*
An application can define compressed texture images by providing a texture image stored in a specific compressed image format. This extension does not
* define any specific compressed image formats, but it does provide the mechanisms necessary to enable other extensions that do.
*
*
An application can also define compressed texture images by providing an uncompressed texture image but specifying a compressed internal format. In this
* case, the GL will automatically compress the texture image using the appropriate image format. Compressed internal formats can either be specific (as
* above) or generic. Generic compressed internal formats are not actual image formats, but are instead mapped into one of the specific compressed formats
* provided by the GL (or to an uncompressed base internal format if no appropriate compressed format is available). Generic compressed internal formats
* allow applications to use texture compression without needing to code to any particular compression algorithm. Generic compressed formats allow the use
* of texture compression across a wide range of platforms with differing compression algorithms and also allow future GL implementations to substitute
* improved compression methods transparently.
*
*
Promoted to core in {@link GL13 OpenGL 1.3}.
