Zoom content instead of changing screen resolution

I'd really love the OS X version of BFP to be fixed so it doesn't change my screen resolution. Any other windows on the computer (eg Finder windows - that program can't be turned off) have their sizes changed when the screen resolution is changed, so when I am done with BFP it's messed up my screen. It also causes programs with things like iCal alarms or any other pop up messages that pop up while BFP is running.

Wouldn't it be possible to use OS X's functions to just zoom up the size of your program so it's full screen for any resolution people are using? I know it's possible with the programming in general as other programs - eg EyeTV, VLC, QuickTime Player, DVD Player, etc - zoom up their content "on the fly" to fit whatever size the screen is set to.
