5743// Idea for a kind of mask buffer
5744// Format of Transparentbuffer (each line):
5745// the first DWORD contains 2 WORDS with Offset of First Non transparent
5746// pixel in the low word and the last non transparent pixel in a row in
5747// the high word. => 0 = line totally transparent!
5748// This limits the max supported width to 2^16 but I thing this is enougth

5750// 1 pixel

5754// Layout of a DWORD:

5756// Each bit in a byte stands for one pixel. MS Bit First
