*
* This table only includes a subset of available internal formats. In
* particular, the table does not include:
* -- unsized formats (e.g.: GL_RGBA)
* -- depth or stencil formats
* -- compressed formats
* -- formats with a component with a bitwidth that is not a multiple of 8
* (e.g.: GL_RGB5_A1).
* -- formats with a total bitwidth that is not a multiple of 32
* (e.g.: GL_RGB8).
*
* Test that the required GL_INVALID_ENUM error is generated for these formats.
