ImageData broken for small images...

[Brian Yennie]

Sounds like 'Zilla material to me, but if you're desperate for a dirty 
workaround, you could try taking your 4x4 (or less) imageData and 
scaling it byte-by-byte to 8x8, and then scaling the target image 
object down again by 50%. You'd still have 8x8 imageData, but a 4x4 
image... (like I said, dirty...). That should work at least if the 
small imageData is truly the source of engine problems.
