These methods operate directly on ``pipe_resource`` objects, and stand
apart from any 3D state in the context. Blitting functionality may be
moved to a separate abstraction at some point in the future.
``surface_fill`` performs a fill operation on a section of a surface.
``resource_fill_region`` performs a fill operation on a section of a resource.
``surface_copy`` blits a region of a surface to a region of another surface,
provided that both surfaces are the same format. The source and destination
may be the same surface, and overlapping blits are permitted.
``resource_copy_region`` blits a region of a subresource of a resource to a
region of another subresource of a resource, provided that both resources have the
same format. The source and destination may be the same resource, but overlapping
blits are not permitted.
``resource_resolve`` resolves a multisampled resource into a non-multisampled
one. Formats and dimensions must match. This function must be present if a driver
supports multisampling.
The interfaces to these calls are likely to change to make it easier
for a driver to batch multiple blits with the same source and
