r2159 - Viewport Resize Filter

[Hykem]

As of r2159, I've decided to start investigating a more complete way to integrate screen resizing with JPCSP.
Starting from gid's suggestion, a viewport resize filter has been implemented, like the anisotropic, but this one is a little different.
First, it acts independently, so you can have both the anisotropic and this one working. Then it's purpose is to be used with the "Resize" menu.
You can find it under Options > Video > Filters > Resize.

Basically, if you leave this filter off, resizing will be processed like it has always been. The LWJGL canvas simply streches, which allows you to freely resize the emulator's window, but has the major drawback of corrupting a ton of graphics. The most common situation has been the abnormal double resizing in certain 3D games.

In order to avoid this, the whole graphical context must be resized properly, so, if you toggle the resize filter on, you'll be limited to work with fixed aspect ratios of 1x, 2x and 3x times the regular PSP screen (don't worry, there are plans to extend this functionality, specially to full screen).

Any attempts to expand the window with the filter on, will just reveal a black rectangle around the main screen, just like what happens with "Only GE graphics" on. However, the screen will now properly resize everything and no longer cause those issues.

There are still some textures that aren't displaying correctly, due to the fact that some fixed constants are being used in the VideoEngine, but after correcting this they should show just fine. Any testing to trace these down would be appreciated. Thanks!

r2163:
I can't get it to work at all - no matter what with "resize" filter on, gfx are never shown, just black screen (fullscreen, windowed 1x, windowed 2x, etc.). I've spent an hour testing a ton of scenarios and my games and can not get this to work nor do I notice any other display improvements.

That really is odd...
Could you please try to run a game, with the filter set to off, then resize and only then turn the filter on? Thanks!

GFX freeze as soon as the filter is activated.

works semi-ok here, try starting the game, turn resize on, then use the resize 2x, 3x ..etc to get it to display (don't manually resize)

everything seems to resize better then before but some games get glitchy

The second I turn on "Resize" the gfx freeze. The game continues (audio) but the display is toast. Something is simply wrong here.

I've even tried with JPCSP extracted to a new folder (fresh install), and the same thing - if "resize" is ever turned on, no gfx will ever display. Even tried both 32/64 bit. Gotta be a hardware/environment difference of some kind.

Yea I get a black screen too as soon as I enable resize, but it gets fixed when I select 2x , 3x

My testing on r2163 reveal that :
1. With 1x size and resize enabled you get black screen.
2. With 2x,3x and resize enabled there are a lot of black lines under menu items in various games (upscaling bugs?).
3. The 2x,3x options now resize to the correct aspect ratio (was about goddamn time);
4. If you do not enable the resize filter but stretch the window the render area remains small (1x).
5. A lot of games now blink like hell (try P3P) with resize on.
6. UNRELATED TO RESIZING : In the movies of Tantei Opera Milky Holmes the sound is horribly desynced (the video is like 3-4 seconds ahead).
L.E: Oh wait there's more:
7. Resetting any game does not work anymore i press reset then run and the emulator locks up.

Verdict : still UGLY Try again.
