- GreGetDIBitsInternal:
- Prevent an access violation in DIB_FreeConvertedBitmapInfo by initializing the bit count before calling DIB_ConvertBitmapInfo and setting clrUsed.
- Validate input parameters and return correct values - only return number of scan lines if bits are not null and bpp is not zero. Otherwise return 1 on success.
- We now pass more gdi32:GetDIBits and gdi32:bitmap tests.
