/**
* \file no_s3tc.c
* Test program to verify the behavior of an OpenGL implementation when
* an application calls \c glCompressedTexImage2D with an unsupported (but
* valid) compression format. The most common example is calling it with
* \c GL_COMPRESSED_RGBA_S3TC_DXT1_EXT when GL_EXT_texture_compression_s3tc
* is not supported.
*
* This tests Mesa bug #1028405.
