over to new system. Need to update documentation and address some remaining vestiges of old system such as CursorRec structure, fb "offman" structure, and FontRec privates.

*
|
|
* Cursor support for Darwin X Server
|
|
*
|
|
* Three different cursor modes are possible:
|
|
* X (0) - tracking via Darwin kernel,
|
|
* display via X machine independent
|
|
* Kernel (1) - tracking and display via Darwin kernel
|
|
* (not currently supported)
|
|
* Hardware (2) - tracking and display via hardware
|
|
*
|
|
* The X software cursor uses the Darwin software cursor
|
|
* routines in IOFramebuffer.cpp to track the cursor, but
|
|
* displays the cursor image using the X machine
|
|
* independent display cursor routines in midispcur.c.
|
|
*
|
|
* The kernel cursor uses IOFramebuffer.cpp routines to
|
|
* track and display the cursor. This gives better
|
|
* performance as the display calls don't have to cross
|
|
* the kernel boundary. Unfortunately, this mode has
|
|
* synchronization issues with the user land X server
|
|
* and isn't currently used.
|
|
*
|
|
* Hardware cursor support lets the hardware handle these
|
|
* details.
|
|
*
|
|
* Kernel and hardware cursor mode only work for cursors
|
|
* up to a certain size, currently 16x16 pixels. If a
|
|
* bigger cursor is set, we fallback to X cursor mode.

Realizing the Darwin hardware cursor (ie. converting from the
|
|
X representation to the IOKit representation) is complicated
|
|
by the fact that we have three different potential cursor
|
|
formats to go to, one for each bit depth (8, 15, or 24).
|
|
The IOKit formats are documented in IOFramebufferShared.h.
|
|
X cursors are represented as two pieces, a source and a mask.
|
|
The mask is a bitmap indicating which parts of the cursor are
|
|
transparent and which parts are drawn. The source is a bitmap
|
|
indicating which parts of the non-transparent portion of the the
|
|
cursor should be painted in the foreground color and which should
|
|
be painted in the background color. The bitmaps are given in
|
|
32-bit format with least significant byte and bit first.
|
|
(This is opposite PowerPC Darwin.)
