It actually removes the previous hack that read the full target.
Unfortunately snowblind engine game uses big target so the read is very big too (1280x448)
which is killer for the perf. Whereas the game requires only 24x12 texels
Give a 2x speed boost on Champion of Norrath !!!
Games uses very special texture with a lots of repeating.
It is much faster to send the full texture rather than trying to partially invalidate it.
On my gs dump:
FPS: 29 => 68 !
* Greatly reduce the number of clut read (factor 10x)
* Avoid to get wrong TEXA texture in the cache.
* Fix "jump depends on uninitialized variable" Valgrind warning.
Fix#748
I try my best to avoid any breakage of DX but please test it too.
Game can directly uploads a background or the full image in
"CTRC" buffer. Previous code was a full black screen.
It will also avoid various black screen issue in gs dump.
hidden option: preload_frame_with_gs_data
Note: impact on upscaling was not tested and it's likely broken
Improve the rendering in MGS3 (even if the game is still broken
due to others TC issues)
// Typical bug (MGS3 blue cloud):
// 1/ RT used as 32 bits => alpha channel written
// 2/ RT used as 24 bits => no update of alpha channel
// 3/ Lookup of texture that used alpha channel as index, HasSharedBits will return false
// because of the previous draw call format
//
// Solution: consider the RT as 32 bits if the alpha was used in the past
When the RT is used as an input texture, we need to rescale it.
Previous behavior was to always uses a linear filtering (more smooth).
Unfortunately it broke some games that expected an exact value like Star Ocean 3
This commit will disable the linear filtering in normal filtering mode (filter = 0
or filter = 2)
This way, shadow of Star Ocean 3 will appear correctly in upscaling (not
100% perfect but can't do better)
Note: SO3 only requires a nearest sampling of the alpha channel but
I don't know the behavior for others games.
Slight adjustments to positions in the GUI also (OCD'd the spacing a little :P)

Another refinement to the Wild Arms hack by KrossX.
The hack now only applies to one kind of geometry (sent using the unpacked UV handler).
This works nicer in Wild Arms as it fixes "jumpy" characters.

Adding KrossX's Wild Arms text alignment hack to the new dialog box. This hack is actually very interesting for a number of games. It should work well in cases where game designers adjusted everything pixel perfect for the GS, that usually breaks with upscaling.
It should be generalized and renamed later.

Committing a hack KrossX prepared (thanks) ;)
It can be used to fix bad character sprites in Gust games.

- Allow filtering setting for native resolution hardware rendering, as it's not tied to the resolution.
- Add ST / UV coordinate tweaking defines to more easily debug small rendering glitches.
- Add a define to bypass the hardware renderer texture cache. With this enabled, speed drops to slower than software rendering.
It fixes nearly all hardware rendering issues though and can be used to see how games *would* look if we had a new cache ;)
Thanks for the help, sudonim :)

- GSWnd is not implemented, no config dialogs either
- no output, just the null device
- threading classes were not tested (my first experience with pthread)

- Moved the offset hack to CreateSource(), it can work a bit more selectively there.

* Removed GSTextureFX classes
* Built shaders right into GSState classes, using GSStateDX as an interface, so that all shader caches get auto-destroyed along with GSState.
In addition to being a bit of a code cleanup, it should be a bit more efficient too since all of the extra dereferences to GSState from GSTextureFX have been removed. :)

- trying the dx10.1-only "gather" shader instruction for palletized lookups ("8-bit texture" mode), saves 4 instructions which isn't much but still... (not tested, don't have ati)
- may fix the intel gma "no output" bug (don't have gma either :P)
- and the usual small code optimizations
