GS really uses an invalid texture located at 0.
Improve the rounding for R&C. The idea is to avoid the corner case were only
the corner of the triangle touch the 7/16 edge.
* Always do +1 before the draw call
* Prefix texture name with i (as input) to keep them before the FB
Goal is to ensure that all renderers share the same draw call value.

Hypothesis the m_map array of list contains an invalid pointer
It is populated GSTextureCache::SourceMap::Add based on the coverage. The coverage is based on the offset.
So offset is potentially wrong. As mipmap code hack the offset value. It would be a nice culprit.
This commit avoids a potential bad transition between MIPMAP (which
overwrite the "offset") and the base layer (which wrongly keep an old "offset")
Conclusion, pray for my soul as it is very hard to reproduce
Ratchet & Clank (the third) uses an address of 0 for invalid mipmap.
It would be very awkward to put the middle layer of texture in start of
memory. So let's use this information to correct the lod.
It make the game more robust on the lod rounding
The hack only fix the HW renderer but not the SW renderer. However I'm not sure
the issue is from GSdx.
The hack will disable alpha test that used to generate empty draw call.
At higher resolutions it takes too much time to save a screenshot at the
maximum compression level. So let's allow the user to set the
compression level.
This re-uses the png_compression_level setting. The default compression
level is 1 for speed, but if the user wishes to increase the compression
level (without using an external tool) and doesn't mind if the
screenshot takes more time to save then they can increase the
compression level up to a maximum of 9 (which can take quite a while).
Fixes#1527.
* Improve frame buffer height management on custom resolution. Width seems to be fine with the same size as scaled image output.
* Prevent offset issues on Persona 3 based on the data from merge circuit.
Note: Fixes custom resolution upscaling on ICO 50Hz/60Hz mode when large frame buffer is enabled. previously 60Hz mode only displayed half of the screen and 50Hz mode only worked due to the scissor hack.
Enable it to ensure correct rendering (FMV)
Disable it to reduce GPU/memory requirement
Option will likely be removed when the perf impact will be reduced.
