+ * 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.
