c1df6d7b4e Work around PowerVR's shader compiler.
This bug has been reported to IMGTec at https://pvrsupport.imgtec.com/ticket/472

The basic idea of the bug is that if you're doing a bitwise and  of a constant value vector with a constant scalar value, this causes PowerVR's shader
compiler to fail out with a very non-descriptive message.
Working around the issue by making the value a vector that it is being masked by.

3d98f6ab9f PixelShaderGen: apply zfreeze before ztextures
The zfreeze option freezes the depth plane of the rasterization.
So this is done before the TEV stages, where the z-textures are applied.

4cdf9f543f Partially fix WWE12 titantron videos.
The obvious question here is, why does it matter if we round or truncate?
The key is that GC/Wii does fixed-point interpolation, where PC GPUs do
floating-point interpolation. Discarding fractional bits makes the conversion
from floating-point to fixed point give more consistent results.

I'm not confident this is really the right fix, or that my explanation is
completely correct; ideally, we don't want to depend on floating-point
interpolation at all.

88c7afd315 Make zfreeze use screenspace coordinates independant of IR.
OpenGL requires the y coordinates to be flipped.

Also refactored PixelGen code to remove duplicate code.

418296961c Fix various issues with zfreeze implemntation.
Results are still not correct, but things are getting closer.

 * Don't cull CULLALL primitives so early so they can be used as reference
        planes.
 * Convert CalculateZSlope to screenspace coordinates.
 * Convert Pixelshader to screenspace coordinates (instead of worldspace
        xy coordinates, which is totally wrong)
 * Divide depth by 2^24 instead of clamping to 0.0-1.0 as was done
        before.

Progress:
 * Rouge Squadron 2/3 appear correct in game (videos in rs2 save file
         selection are missing)
 * Shadows draw 100% correctly in NHL 2003.
 * Mario golf menu renders correctly.
 * NFS: HP2, shadows sometimes render on top of car or below the road.
 * Mario Tennis, courts and shadows render correctly, but at wrong depth
 * Blood Omen 2, doesn't work.

937844b9e3 Initial port of zfreeze branch (3.5-1729)
Initial port of original zfreeze branch (3.5-1729) by neobrain into
most recent build of Dolphin.

Makes Rogue Squadron 2 very playable at full speed thanks to recent core
speedups made to Dolphin. Works on DirectX Video plugin only for now.

Enjoy!  and Merry Xmas!!

1b771deb56 Move worldpos into it's own varying.
Previously it was packed into spare slots in clippos.xy and normal.w,
but it's ugly and more importantly it's causing bugs.

This was discovered during the debugging of a zfreeze branch, which
expected clippos.xy to be xy position coordinates in clipspace (as
the name suggested).

Turns out the stereoscopy shader had also run into this trap, modifying
clippos.x (introducing errors with per-pixel lighting).

This commit has been moved outside of the zfreeze PR for fast merging.

5c3bbf7409 Works around broken Intel Windows video drivers.
Just use regular boolean negation in our pixel shader's depth test everywhere except on Qualcomm.
This works around a bug in the Intel Windows driver where comparing a boolean value against true or false fails but boolean negation works fine.
Quite silly.

Should fix issues #7830 and #7899.
