- '''OpenGL extension EXT.texture
-
- Overview (from the spec)
-
- The original intention of this extension was simply to support various
- numeric resolutions of color components in texture images. While it
- accomplishes this, it also accomplishes a larger task, that of
- formalizing the notion of an internal format for images, corresponding
- to the external format that already existed for image data in host
- memory. This notion of an internal image format will be used
- extensively in later extensions, especially those concerned with pixel
- manipulation.
-
- The idea of an internal format is simple: rather than treating a
- retained image as having 1, 2, 3, or 4 components, treat it as though
- it has a specific format, such as LUMINANCE_ALPHA, or just ALPHA. Then
- define the semantics of the use of internal images with these formats in
- a consistent way. Because texture mapping is already defined in GL, the
- semantics for internal-format images were chosen to match those of the 1,
- 2, 3, and 4 component internal images that already existed. The new
- semantics are a superset of the old ones, however, so this extension
- adds capabilities to GL, as well as allowing internal resolutions to be
- specified.
-
- This extension also defines a robust method for applications to
- determine what combinations of texture dimensions and resolutions are
- supported by an implementation. It also introduces a new texture
- environment: REPLACE_EXT.
-
- The official definition of this extension is available here:
