We are removing MSAA for the following reasons:
1. It's broken
2. Fixing it would mean it would perform as well as FSAA, which defeats the purpose of having it
3. It's only supported by DX and Windows
4. Reduction in code complexity
Press F to pay respect
Idea is to disable multiple features in 1 option to avoid gui clutter.
Unscale Point and Line:
This partially reverts PR #2710 restoring Unscale Point and Line but as a disable option.
It can help Xenosaga games.
GS Memory clearning:
This disables GS memory clearing to be done on the CPU, by default both gpu and cpu do memory clearing
which is more accurate.
It can help Kingdom Hearts games.
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.
