Set the compressed texture format to use, based on the formats you have, and the formats supported by the hardware / browser.
Khronos Texture Container (.ktx) files are used to support this. This format has the advantage of being specifically designed for OpenGL. Header elements directly correspond to API arguments needed to compressed textures. This puts the burden on the container generator to house the arcane code for determining these for current & future formats.
