[GD-Windows] GetDIBits() return values

[Brian H. <ho...@bo...>]

On occasion GetDIBits() returns 0, indicating failure, but 
GetLastError() returns 0, indicating success.  The dimensions I pass 
in are scan start=3D0,scanlines=3D12.  Everything seems to work fine, but 
very occasionally (< 1% of the time) I get a return value that !=3D 12.

Anyone know under what conditions this might happen?

Thanks,

Brian
