cameratexture CAMTEX 128 96 fit 64 48
in zdoom 96x this indeed works as intended, fitting the 128x96 texture into the 64x48 area completely. but in gzdoom, it looks like this:

it doesn't even matter what numbers I use; I can make it perfectly square or even not scale it at all, same kind of thing.
also happens on others maps that have camera textures in them, like grbtest.wad from zdoom96x.
this also happens on my brother's computer (Duron ~800, Win 98, Geforce 2) as well as mine (Athlon 64 2800+, WinXP, Radeon 9600XT), so it's not just me.
funny it would slip, but..there it is..
