[PD] Gem screensizes

hi trevor,

yes. some problems could be caused by the graphic driver. i had a problems
that squares looked like rectangles in fullsreen mode...

to convert mouse-coordinates(pixels) to "gem-coordinates" i use

[inlet] minus (windowsize in pixel / 2) minus 1 multiplied by 4

[inlet]
|
[/ 100] (screensize is 200)
|
[- 1]
|
[* 4]
|
[outlet]

i don't know, if that is an official algorithm, it seems to work with sizes
200, 400, 600 but has some rounding errors with some other screensizes...

how do you maximze? this should work, at least it does with XP... btw, there
is also a "fullscreen 1" command. for fullscreen mode.
