Summary	01997: Screen stretch and position distorts screen shots.
Description	Previous to 0.126, a screen shot would reflect the exact pixel size of the display. If the game's resolution is 320x240, this is also the size of the screen shot taken. With 0.126, if you use custom screen position and stretch settings, screen shots will appear off center, distorted or resampled, depending on the settings used when the shot was taken. The screen shot still maintains the original width and height, but the offset or aspect of the image is affected.
Steps To Reproduce	While game is running, use the '~' key to activate the onscreen menu, change the screen position or stretch. Take a screenshot using the F12 key.

If you took a shot with 0.125, for example, with a screen offset - your snapshot would appear offset as well. All adjustments are now carried over (gamma/brightness/etc.). There is one problem with bezels + screenshots: If you load artwork but choose to "Hide Bezels" for example, the screenshot will still show the bezel. A command line "-nouse_bezels" works as expected and does not show the bezel on screenshots. I'd like Aaron to identify/comment on if this is new functionality to take advantage of the new snap commands or not.

This doesn't particularly concern me, and is difficult to fix. If you want native pixel screenshots, don't mess with that stuff. As for the Hide Bezels options -- the screenshots only obey what was on the command line. They are not dynamically altered based on any changes you do on the fly.
