/**

|
|
* 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.
