You'd have to talk to the compiz/beryl folks regarding the texture
size limit.  I think they may be working on some solution for that.
Regarding the coordinate limits, they are 4096x4096 in theory IIRC,
but I don't think all the bits are useable.  I'm not sure what the
actual useable limits are on which chips.  You'd have to try it and
see.
