AFAIR, this kind of library only makes sense when the related
application was
wrongly coded, because most hardware support s3tc compress in hardware despite
this is disabled by default (can be enabled with driconf). This library
implement this feature in software as a fallback for wrongly codec application.
Huh? What the hardware does is texture *de*compression. The point of texture
compression is that you compress the textures before uploading them to the
hardware to save bus bandwidth.
The only way you don't need S3TC compression support in the driver is to store
the already compressed textures in your program (in addition to the
uncompressed ones, as not all hardware supports S3TC). Very few apps do that.
