8ffa3fb9fa the official system palette also has the 0xff entry (B_TRANSPARENT_MAGIC_CMAP8) with alpha = 0

359c905c57 offscreen bitmaps work, tested on Haiku as well, supports all colorspaces that BBitmap::ImportBits() supports. It uses a fallback for non-B_RGB(A)32 bitmaps. Added support for B_SUB_PIXEL_PRECISION view flags, though it is a bit hacky, since I had to add it to LayerData, even though it is not a true part of stack data. Added Layer::SetFlags() to enforce code path and update fLayerData. Cleaned up DisplayDriverPainter and DisplayDriver API (changed some const BRect& rect to simply BRect rect in order to be able to reuse it in the code), moved Painter.h, the test environment only draws the changed part of the frame buffer again - this causes a lot less CPU overhead, Painter special cases stroke width of 1.0 to use square caps, which is similar to R5 implementation and removes a lot of problems with non-straight line drawing, ServerWindow uses the DisplayDriver from it's WinBorder instead of the one from the Desktop (needed for offscreen windows, which have their own DisplayDriverPainter), it also checks for GetRootLayer() == NULL, because offscreen layers are not attached to a RootLayer, there was a fix for scrolling which worked at least in the test environment, it is now defunced, because Adi moved _CopyBits to Layer... I need to reenable it later, LayerData has no more fEscapementDelta, also fixed fFontAliasing (which was thought to overriding the font flags, and now works as such again), Desktop initialises the menu_info and scroll_bar_info stuff, which makes ScrollBars work actually... hope I didn't forget something.

d039af7469 Reverted to the previous algorithm, which is just another version of the same one: they produce slightly different results, but this one should be faster as it doesn't use divisions.

6ec6f3f831 Better color distance-measuring algorithm, taken from here: 
http://www.stud.uni-hannover.de/~michaelt/juggle/Algorithms.pdf.

Still not 100% identical to be's one, but much closer.
Small cleanups.

1f1ed1c62c Generate the inversion map. 
Note that the inversion_map and the index_map aren't the same as in Beos, due to bugs (or different behaviour) in color_distance.

509db2a318 Generate the index map using some code stolen from BBitmap. The Mandelbrot sample app starts looking good. Only the inversion map is missing now

7475dcdf3a Added an app server command to retrieve the color map. Made some adjustments to SystemPalette.cpp, implemented support for it in BPrivateScreen. Moved get_scs() a bit down to avoid a deadlock. Note that getting the colormap doesn't work due to port capacity limit (?)
