Pascal Massimino 827a307fec BMP enc: fix the transparency case 
When transparency is present, it's not enough to just write 32bpp samples.
One need to use the full BITMAPV3INFOHEADER syntax and specify the
masks for BGRA.

 see https://en.wikipedia.org/wiki/BMP_file_format#Pixel_storage

Also remove the height-flip trick and write samples bottom-to-top instead.
