Support capture of SDL applications

[martini]

Hi Gregg

I noticed that Gotcha (as several other screen capture tools) does not capture applications and games that uses SDL. (I think that SDL is the issue). I'm using Gotcha 2.01

For example today I was trying ScummVM in window mode and the screen captures of the screen does not shows the game.

Do you think it can be possible to support this kind of capture in Gotcha?

Regards
