4617// Purpose : Do a blit using the precalced Transbuffer
4618// That is the only way to do fast blits if a colorrange is used
4619// and we can find totally transparent lines and don't blit them
4620// and detect if the part of the line is transparent
4621//
4622// Idea for a kind of mask buffer
4623// Format of Transparentbuffer (each line):
4624// the first DWORD contains 2 WORDS with Offset of First Non transparent
4625// pixel in the low word and the last non transparent pixel in a row in
4626// the high word. => 0 = line totally transparent!
4627// This limits the max supported width to 2^16 but I thing this is enougth
4628// The size per line is 1+((Width+31) & ~31) DWORDS => each Bit represents
4629// 1 pixel
4630//
4631// TransparentBufferCreate(lpDDSurfaceDesc->dwWidth, lpDDSurfaceDesc->dwHeight);
4632//
4633// Layout of a DWORD:
4634// UUVVWWXX dword is processed LS Byte FIRST ...
4635// Each bit in a byte stands for one pixel. MS Bit First
4636//
4637// example: Bitmap (16x5) (X= opaque, . = Transparent)
4638// ...XX...XX....XX
4639// ..XXXX....XXXX..
4640// ................
4641// .........XXXXXX.
4642// ...XX...X......X
4643//
4644// Transparent buffer (2DWORDS) per line
4645//
4646// 0x00100003, 0x0000C318
4647// 0x000E0002, 0x00003C3C
4648// 0x00000000, 0x00000000
