Use floor() to convert to int (per Mark Kildard and the SI).
Also, change translate_id() to return a signed integer since we may be
offsetting from GL_LIST_BASE.

GL_REPLACE_EXT comes from the ancient GL_EXT_texture extension. Found an old demo that
actually uses it.
The values of the GL_REPLACE and GL_REPLACE_EXT tokens is different, unfortunately.

Instead of postponing the error from missing pkg-config macros to when
configure is run, make autoconf exit by using m4 macros.

Test that modifications to a texture object in one rendering context are seen
in a second rendering context.
Press 't' to change the texture's image/colors.

Since the autoconf config inherits from default, we don't need to
duplicate and substitute the MESA_* version numbers in configure.ac.
The version number is only needed in configure for the help text.

Fixes problem with bitmaps jumping around by one pixel depending on window
size. The rasterpos is often X.9999 instead of X+1.
Run progs/redbook/drawf and resize window to check.

The previous default these days served mostly to cause artifical problems with
GLX compositing managers like compiz (see e.g.
http://bugs.freedesktop.org/show_bug.cgi?id=10501).

The 32-bit immediate value in the i965 instruction word must contain two
copies of any 16-bit constants. brw_imm_uw and brw_imm_w just needed to
copy the value into both halves of the immediate value instruction field.

e.g. bridge of fate.
If vs output is big, driver may fall back to use 8 urb entries for vs,
unfortunally, for some unknown reason, if vs is working at 4x2 mode,
8 entries is not enough, may lead to gpu hang.

Makes state emission into a 2 phase, prepare sets things up and accounts
the size of all referenced buffer objects. The emit stage then actually
does the batchbuffer touching for emitting the objects.
There is an assert in dri_emit_reloc if a reloc occurs for a buffer
that hasn't been accounted yet.

This reverts commit 3158e981f5f37768e9b04765704b9eaece8b899b.
rhw issue has gone away on IGD.

batchbuffer > aperture size.
So with compiz on Intel hw with fake bufmgr, opening 4 firefox windows at 1680x1050 and hitting alt-tab, could cause the batchbuffer to try and reference more than the 32MB of RAM allocated.
Fix 1:
Fix 1 is to pre-verify the list of buffers against the current batchbuffer and if it can't possibly fit in the aperture to flush the batchbuffer to the hardware
and try again. If the buffers still can't fit well then you are hosed as I'm not sure there is a nice way to tell anyone.
Fix 2:
Next problem was that even with a simple check for total < aperture, we ran
into fragmentation issues, this meant that half way down a set of buffers,
we would fail as no blocks were available. Fix this by nuking the memory
manager from orbit and letting it start again and relayout the blocks in a
manner that fits.
Fix 3:
Finally the initial problem we were seeing was a memcpy to a NULL backing store.
We seem to end up with a texture at some point that never gets mapped but ends up with data in it. compiz al-tab icons have this property. So I created a card dirty bit that memcpy's any buffer that is !static and is written to back to memory. This probably is wrong but it makes compiz work for now.
Caveats:
965 support is still fail.

due to the two read ports limit into temp memory may need the MAD_2 instruction
for the second instruction of the decomposed XPD.
While here, also try to avoid MAD_2 for MAD if all 3 inputs are temps but the
temps aren't actually distinct.
