Gregory Hainaut e66aac8ab7 gsdx-hw: add an hidden option to preload the final frame with GS mem data
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

Gregory Hainaut 85543db094 gsdx-tc: trace the alpha channel update in TC
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

Gregory Hainaut 580d177951 gsdx: improve commit 11708486d8

Gregory Hainaut 11708486d8 gsdx: allow to control the filtering of texture cache
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)

sudonim1@gmail.com 0d9eca8668 88GSDX: Removed the "sprite hack" as it should be obsolete, fixed the vertex shader selector key function (the pixel shader was broken in the same way but with the "sprite hack" removed it doesn't matter now).

sudonim1@gmail.com e8257df98d GSDX: made the paletted texture handling in the cache a bit more sensible to my eyes and implemented interpolation of palette entries for pixels in paletted textures when using the 8 bit textures option. Regressions in some games I think, such as Virtual On (which is very broken anyway), need to investigate what made them work (to some degree) before. Seems to change some performance characteristics favourably to my surprise, but I might just be bad at remembering framerates.

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.

ramapcsx2 b25aec19c1 GSdx:
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.

gabest11 5325f9b490 GSdx: Small optimizations here and there, just saving changes before trying to add an index buffer, that might help reducing load on the main gs thread a bit. That's where I think the bottleneck currently is in games with high polygon count.

ramapcsx2 5785ba7914 GSdx:
- 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 :)

Jake.Stine e4c0dfb6d3 GSopen2: Fixed GSdx so that it complies with the implied intent of the PS2E plugin API, where GSopen and GSclose retain the current GS emulation state. This required a couple significant changes:
* 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. :)
