2995f43728 Add a 2x by 3x line3x mode for the PSP's 480x272. 
Temporary commit, I don't want people to use this mode until I can
implement 3x by 3x line3x.

71147c44dd Add 480x272 sampling/optimized mode for the PSP. 
This commit adds both a 480p input sampling mode and line2x optimized
mode for the PSP's 480x272 picture. The line2x optimized mode is enabled
automatically when the sampling mode is selected.

When in-game, the PSP outputs a letterboxed 480p picture. The active
portion of the screen is 480x272, but is treated as 480p (480x720).

In addition, a line2x optimized mode is added which produces a 960x544
output picture, which if desired the top + bottom pixels can be dropped
producing a 960x540 (qHD) picture.

To generate a qHD picture, use the following settings:

V. Active: 270
V. Backporch: 135

b1892079d8 select 576p / 800x600 preset based on refresh rate 2020-04-28 22:31:57 +03:00

bab85e713b Increase max V. Backporch value from 63 to 236 
This change allows highly letterboxed content (e.g. the PSP's 480x272
picture in a 720x480 frame) to be "zoomed" to a full screen picture by
treating the letterbox as horizontal and vertical backporch.
