Tiger Lake and onward allow drivers to specify a compression format
independently from the surface format. So, even if the surface format
changes, hardware is still able to determine how to access the CCS.

The sampler's decompressor seems to lack support for some types of
format re-interpretation. Use the more capable decompressor for these
cases. This will be needed to avoid regressing piglit's
arb_texture_view-rendering-formats in later commits.

according to KHR_gl_texture_3D_image:
If <target> is EGL_GL_TEXTURE_3D_KHR, <buffer> must be the name of a
complete, nonzero, GL_TEXTURE_3D (or equivalent in GL extensions) target
texture object, cast
into the type EGLClientBuffer. <attr_list> should specify the mipmap
level (EGL_GL_TEXTURE_LEVEL_KHR) and z-offset (EGL_GL_TEXTURE_ZOFFSET_KHR)
which will be used as the EGLImage source; the specified mipmap level must
be part of <buffer>, and the specified z-offset must be smaller than the
depth of the specified mipmap level.
thus a 2d view of a 3d surface is not only legal, it's part of the spec and
must be supported when available

When CCS compression first came out on Skylake, we referred to it as
"renderbuffer compression", or RBC for short. However, that name has
long since fallen out of favor, and we refer to it as CCS nearly
everywhere.
This patch renames DEBUG_NO_RBC to DEBUG_NO_CCS inside the codebase
for clarity, and adds INTEL_DEBUG=noccs. The legacy INTEL_DEBUG=norbc
name continues to work, because it's one line of code and having both
names makes our lives easier in the interim.

We're going to start programming this field for media compression, so

MediaCompressionFormat field. Either option seems fine, so we go with
