glsl-derivs would add 40.0, 0.0, and 1.0 in order. When we went
looking for 0.0, we'd find it in the second slot of the param, and use
it, but param->Size would still be 1. When we went to add 1.0 and
didn't find it, we'd put allocate it to that second slot and the 0.0
would actualy end up being 1.0.
Fixes glsl-derivs, glsl-deriv-varyings.
_mesa_glsl_parse_state should be the parent for all temporary allocation
done while compiling a shader. glsl_shader should only be used as the
parent for the shader's final IR---the _result_ of compilation.
Since many IR instructions may be added or discarded during optimization
passes, IR should not ever be allocated to glsl_shader directly.
Done via sed -i s/talloc_parent(state)/state/g and s/talloc_parent(st)/st/g.
This also removes a ton of talloc_parent calls, which may help performance.
When compiled with the more aggressive compiler warnings such as
-Wshadow and -Wempty-body the libtess code gives a lot more
warnings. This fixes the following issues:
* The 'Swap' macro tries to combine multiple statements into one and
then consume the trailing semicolon by using if(1){/*...*/}else.
This gives warnings because the else part ends up with an empty
statement. It also seems a bit dangerous because if the semicolon
were missed then it would still be valid syntax but it would just
ignore the following statement. This patch replaces it with the more
common idiom do { /*...*/ } while(0).
* 'free' was being used as a local variable name but this shadows the
global function. This has been renamed to 'free_handle'
* TRUE and FALSE were being unconditionally defined. Although this
isn't currently a problem it seems better to guard them with #ifndef
because it's quite common for them to be defined in other headers.

The target supports OpenVG on Windows with software rasterizer. The
egl_g3d_loader defined by the target supports arbitrary client APIs and
window systems. It is the SConscript that limits the support to OpenVG
and GDI.
This commit also fixes a typo in gdi backend.
Patch from Brad Smith <brad@comstyle.com>
The attached patch allows the GL_OES_query_matrix function to use the
systems fpclassify() for OpenBSD and NetBSD.
This undoes part of commit 8be645d53a
and fixes fd.o bug 28822 as well as other regressions.
The 'draw' module may issue additional state-change commands while
we're inside the draw_arrays/elements() call so it's important to
check for updated state at this point.
