[Crash when rotating images with more than 2^29 pixels]

Assuming the rotate operation is backed by an array or similar data type, the solution may involve setting this option:

This would extend the limit 4 fold to 2^31 pixels per image (~46,000x46,000) which is likely more than even I would need. 

[Crash when rotating images with more than 2^29 pixels]

If I attempt to bring up the rotate layer dialog, I get an OverflowException if the canvas size is large enough.  The error seems to happen when the total memory usage exceeds the 31 bit address space limit:

 

23170x23170 @ 4 bytes/pixel = 2^31 bytes = no crash

 

23171x23171 @ 4 bytes/pixel = 2^31 + 8 bytes = crash

 

 

Thanks!
