[Mesa-dev] [PATCH 3/3] i965: Bump MaxTexMbytes from 1GB to 1.5GB.

[Kenneth Graunke]

Even with the other limits raised, TestProxyTexImage would still reject
textures > 1GB in size.  This is an artificial limit; nothing prevents
us from having a larger texture.  I stayed shy of 2GB to avoid the
larger-than-aperture situation.

For 3D textures, this raises the effective limit:
 - RGBA8:   645 -> 738
 - RGBA16:  512 -> 586
 - RGBA32F: 406 -> 465
