Hi guys,
I just ran the compression-test and noted the next results:
When I run test on Intel® HD Graphics 4600 (Haswell) with master version of
mesa - I see next response - "12 generic compressed texture formats available:
 086b0: GL_COMPRESSED_RGB_FXT1_3DFX (compressed format)
 086b1: GL_COMPRESSED_RGBA_FXT1_3DFX (compressed format)
 083f0: GL_COMPRESSED_RGB_S3TC_DXT1_EXT (compressed format)
 083f2: GL_COMPRESSED_RGBA_S3TC_DXT3_EXT (compressed format)
 083f3: GL_COMPRESSED_RGBA_S3TC_DXT5_EXT (compressed format)
 09274: GL_COMPRESSED_RGB8_ETC2 (compressed format)
 09278: GL_COMPRESSED_RGBA8_ETC2_EAC (compressed format)
 09270: GL_COMPRESSED_R11_EAC (compressed format)
 09272: GL_COMPRESSED_RG11_EAC (compressed format)
 09271: GL_COMPRESSED_SIGNED_R11_EAC (compressed format)
 09273: GL_COMPRESSED_SIGNED_RG11_EAC (compressed format)
 09276: GL_COMPRESSED_RGB8_PUNCHTHROUGH_ALPHA1_ETC2 (compressed format)
compressed_texture is not a compressed texture file, or is corrupted
failed to load texture compressed_texture"
I see the same response on 18.3.2 version of the mesa on this machine.

Also, I see the same response on Intel® UHD Graphics 620 (Kaby lake) and Intel®
HD Graphics 3000 (Sandy Bridge) with 18.3.2 version and master's version of the
mesa.
Please, confirm - is it correct?
