6bf0f6ae86 meta: Detect currently-unsupported integer CopyTexSubImage and complain. 
This code is unprepared for handling integer (particularly, the
baseFormat of the TexFormat comes out as GL_RGBA, not GL_RGBA_INTEGER,
so the direct call of Driver.ReadPixels crashes due to the int vs
non-int error checking not having happened).  I'm frankly tempted to
convert this code to MapRenderbuffer/MapTexImage rather than doing it
as meta ops, now that we have that support.

Improves the remaining crash in Intel oglconform for int-textures to
just a rendering failure.

NOTE: This is a candidate for the 8.0 branch.

d6c58545a1 mesa: Add the remaining from/to types for GL_EXT_texture_integer (and R/RG). 
This aborts and crashes in intel oglconform's int-textures into being
just rendering failures.  Clamping isn't handled yet.

v2: Add missing "break".
v3: Drop the int/uint distinction, since they don't need different clamping.
NOTE: This is a candidate for the 8.0 branch.

08acd4bd61 mesa: Add support for glGetTexImage on GL_TEXTURE_1D_ARRAY 
Similarly to how we handle this in texstore, we have to remap height
to depth so that we MapTextureImage each image layer individually.

Fixes part of Intel oglconform's int-textures advanced.fbo.rtt

NOTE: This is a candidate for the 8.0 branch.

f6e82cd2a1 i965/gen6+: Work around GPU hangs with logic ops on integer textures. 
This doesn't result in correct rendering -- GL requires that logic ops
work, while the hardware specs say it doesn't do them.  I'm not sure
how we would want to handle this.

NOTE: This is a candidate for the 8.0 branch.

4a1c660599 mesa/gdi: remove wmesa_set_renderbuffer_funcs() function 
The code is no longer relevant.
Note: this driver is probably broken now.  There's no implementation
of ctx->Driver.Map/UnmapRenderbuffer().

1caf698191 swrast: use Map/UnmapTextureImage() in framebuffer map/unmap code 
When we're actually rendering into a texture, map the texture image
instead of the corresponding renderbuffer.  Before, we just copied
a pointer from the texture image to the renderbuffer.  This change
will make the code usable by hardware drivers.
