Thanks for the feedback. I decided to set the maximum to 8192 x 8192 pixels in the new beta which sounds like it should be more than enough for the majority of use cases. It also limits memory usage to 200MB per maximum size bitmap. As for automatic resizing of bitmaps, that would be more complicated to implement and might require rewrites of existing routines. I have added it to my to-do list though. Thanks for your comments everyone.
