Blending isn't valid for integer formats. Rather than having drivers

The flag_rect and flag_buffer fields didn't sufficiently capture
the state changes needed for those resource types. For example,
if a texture binding was changed from a 500x500 rect texture to a
400x400 rect texture we didn't set SVGA_NEW_TEXTURE_CONSTS. But
we need to do that to emit the new texcoord scale factors to the
constant buffers. Rather than track the sizes of all bound
resources, just set the flag if the resource is a rect. Same
story with texture buffers.
Also, since rect/buffer textures are usable with VS/GS shaders,
add SVGA_NEW_TEXTURE_CONSTS to the flags we check for emitting
VS/GS constants.
This seems to help with XFCE / xfwm4 desktop scaling.

This extension provides new GLSL built-in function
beginFragmentShaderOrderingIntel() that guarantees
(taking wording of GL_INTEL_fragment_shader_ordering
extension) that any memory transactions issued by
shader invocations from previous primitives mapped to
same xy window coordinates (and same sample when
per-sample shading is active), complete and are visible
to the shader invocation that called
beginFragmentShaderOrderingINTEL().
One advantage of INTEL_fragment_shader_ordering over
ARB_fragment_shader_interlock is that it provides a
function that operates as a memory barrie (instead
of a defining a critcial section) that can be called
under arbitary control flow from any function (in
contrast the begin/end of ARB_fragment_shader_interlock
may only be called once, from main(), under no control
flow.
