When RandR 1.2's transformation code is enabled, it rotates the cursor image so that it appears upright on a rotated screen. This code completely mangles 2-color cursors on hardware where the the mask and source images are not interleaved due to two problems: 1. stride is calculated as (width / 4) rather than (width / 8), so the expression (y * stride) skips two lines instead of one for every time y is incremented. 2. cursor_bitpos ignores the 'mask' parameter if the hardware doesn't specify any of the HARDWARE_CURSOR_SOURCE_MASK_INTERLEAVE_* flags. To fix this, refactor the code to pass the whole xf86CursorInfoPtr through to cursor_bitpos and compute the correct stride there based on the flags. If none of the SOURCE_MASK_INTERLEAVE flags are set, use the total cursor size to move the 'image' variable into the mask part of the image before computing the desired byte pointer.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
