Feature Request: Optional CRT filter for NTSC mode

[indigodarkwolf]

One of the things I'd like to take advantage of, with there being OpenGL acceleration now, is fragment shaders to apply a display device filter, specifically a CRT filter that can be enabled when outputting in NTSC mode. It would be nice if this were more than just "add scanlines": Color mixing and phosphor glow effects would be good, generally trying to mimic the full texture and feel of a CRT.

and PAL then as well perhaps?

Unfortunately, I don't think the VERA supports PAL output, whereas it definitely supports NTSC output. :/ Someone would have to address that first.

Oh yeah, there's that.
