Comment:

 Currently the background is properly cleared to white in that case, which
 sounds like a reasonable solution.
 We could extend the BMP translator to fully support alpha now, as it is
 available in version 3, 4 and 5 of the header:
 http://msdn.microsoft.com/en-us/library/dd183380(VS.85).aspx
 http://msdn.microsoft.com/en-us/library/dd183381(v=vs.85).aspx

 But it seems not all applications can handle this...
 Closing the ticket as there is no bug here, only missing functionalities
 in the BMP translator.
