Stephan Aßmus 588259b66d various changes to handling custom cursors:
* all cursors owned by a team are visually different,
  or (iaw) an already existing cursor is reused when
  it is set by the client again
* changed various occurances of cursor data from "int8*"
  to "uint8*"
* ServerCursors also remember the R5 data from which
  they were created
* the reference counting and destruction of
  ServerCursors changed: The cursor knows it is attached
  to a CursorManager and one can simply use
  ServerCursor::Acquire() and Release() and the reference
  counting and everything is being taken care of
* destroying a ViewLayer will now correctly release a set
  ServerCursor
* fixed a race condition when setting a cursor through
  BView::SetViewCursor(): If the client code looks like this:

  BCursor cursor(cursorData);
  someView->SetViewCursor(&cursor, false);

  there is a relatively high chance the BCursor destructor
  told the ServerApp thread to destroy the cursor before
  the ServerWindow thread got to "acquire" the cursor for
  use by the view layer. The very same problem is likely the
  reason that SetViewCursor works to unreliably on R5, even
  when the "sync" flag is set to "true" (although it should
  theoretically work in that case).

all these fixes make WonderBrush work fine again with the
new support of custom cursors.... coded by axeld and myself
(the joys of pair programming :-)

..
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.
