Multiply the width x the heigth of the intended output and then multiply
that product by 4. This will give you the amount of RAM (in bytes) needed
to render that image. Of course you also have to add in segment memory,
image filtering memory and any other memory eating things (shadow maps sizes)
Chances are there will be a work around (most likely some type of virtual
memory) sometime in the near future.
