Many applications use multi-pass rendering and require their vertex
shader position to be computed the same way each time. Optimizations
may consider, say, fusing a multiply-add based on global usage of an
expression in a shader. But a second shader with the same expression
may have different code, causing that optimization to make the other
choice the second time around.
The correct solution is for applications to mark their VS outputs
'invariant', indicating they need multiple shaders to compute that
output in the same manner. However, most applications fail to do so.
So, we add a new driconf option - vs_position_always_invariant - which
forces the gl_Position output in vertex shaders to be marked invariant.

we don't trigger the X server overflow checks when the x offset is non-zero.
This just hides the versioning in drisw, and either passes the src_x

Commit a5e733c6b5 fixes the dangling
framebuffer object by unreferencing the window system draw/read buffers
when context is released. However this can prematurely destroy the
resources associated with these window system buffers. The problem is
reproducible with Turbine Demo running with VMware driver. In this case,
the depth buffer content was lost when the context is rebound to a
drawable.
To prevent premature destroy of the resources associated with
window system buffers, this patch maintains a list of these buffers in
the context, making sure the reference counts of these buffers will not
reach zero until the associated framebuffer interface objects no
longer exist. This also helps to avoid unnecessary destruction and
re-construction of the resources associated with the framebuffer.
