| /** |
| * \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. |
