Handle the loader returning a fake front-buffer. Since the driver
never specifically requests a fake front-buffer, the driver assumes
that it will never receive both a fake and a real front-buffer.

Assume that the front-buffer exists even if the server didn't tell the
client that it exists.

Track two flags: whether or not front-buffer rendering is currently
enabled and whether or not front-buffer rendering has been enabled
since the last glFlush. If the second flag is set, the front-buffer
is flushed via a loader call back. If the first flag is cleared, the
second flag is cleared at this time.

Subclassing the window is invasive: we might call an old window proc even
after it was removed. Glut and another bug just in the wrong time was
provoking this. Hooks don't have this problem.
This fixes the random results that were seen when fetching a constant
inside an IF/ELSE clause. Disabling the execution mask ensures that all
the components of the register are written.
Before, the instruction's CondUpdate field was mistakenly effecting the
constant-fetch operation.
Fixes progs/glsl/bump.c demo. But there are some other issues related
to condition flags and IF/ELSE that need investigation...
HW TCL path currently assumed fog, WPOS order. The order was inverted for SW TCL path.
This hopefully fixes rest of fog and WPOS related bugs.
Additionally fix some indentation, don't route unnecessary components of fog coordinates for performance reasons and simplify vertex
attribute emitting for SW TCL path.
Fix wrong attribute emit and revert to previous behaviour of calculating VAP_OUT_VTX_FMT_1 register value.
We can't use r300VAPOutputCntl1 function because it assumes that all texture coords have 4 components and that is the case for HW TCL
path, but not for SW TCL.
