Previous behaviour:
Anisotropic filtering was continuing to run even with Nearest filtering.
On opengl it doesn't run on nearest filtering. The gui for both
renderers also greys out aniso when nearest is selected.
Anisotropic filtering being able to run on palette texture. This caused
to break the rendering on palette textures for games that use it.
PR behavior:
The PR corrects both of these behaviors, Aniso won't run on palette
textures as well as nearest filtering.
Test cases for observing the issues were used: Star Ocean 3, Fifa
Street.
With the sprite hack removed it was no longer possible to toggle this
hack on nvidia gpus, the toggle has been moved to Disable Safe Features.
It some issues caused by the hack in sotc, fatal frame and border offset
issues.
Improved handling of frame buffer copy by accounting for fb read on all slots.
- implement before/after draw functions
- defer setting of resources on the api to just before the draw
- use a bitfield to keep track of set/copied resources
- recycle copies after draw
Fixes: RE4 and Tales of Abyss
Use value of 1 when upscale multiplier is 0 for ScalingFactor, this is
to avoid doing math with 0 in shader.
It helps custom res be less broken. Still not recommended to use custom
res ofc.
Update CopyOffscreen to accept the ps_shader value when doing StretchRect.
This fixes an issue where it was selecting the wrong PS for depth cache read.
Should (hopefully) fix SMT.
Remove DATE shader macro and bit.
Remove useless HasStencil case. If DATE is enabled stencil is also
enabled, this check is useless.
Remove leftover rt and rtCopy code case from d3d9.
Remove traces of rtCopy and sampler in slot 2.
rtcopy
Add support for dss_write.
Enable writing in depth buffer for dss_write,
when depth conversion is active data will be writen in the depth buffer,
if not then use the old method (don't write).
Always enable unscale point and line hack on upscaled resolutions, and
purge the gui option.
It was discussed in the past with Gregoy that it can be enabled without
causing any issues which will be beneficial to getting rid of 1 less
option and fixing a bunch of fmv issues without relying on a gui toggle.
This pull request is for the pending reorganization of the folder structure on GSdx,
making it better organized and easier to work with.
Also remove unused GSTextureFX.cpp file.
