The RandR protocol spec has several requests in support of user-defined
modes, but the implementation was stubbed out inside the X server. Fill out
the DIX portion and start on the xf86 DDX portion. It might be necessary to
add more code to the DDX to insert the user-defined modes into the output
mode list.
When an output no longer reports the current mode, it must still be included
in the list advertised by the X server. Walk the crtcs to ensure it is
included.
Now that resources can be created during server initialization, make sure
the crtc, output and mode resource types are created before attempting to
create associated resources.
xf86 drivers need to create RandR object in the PreInit stage,
before the ScreenRec is allocated. Changing the RandR DIX code
to permit this required the addition of functions that later associate the
objects with the related screen.
An additional change is that modes are now global, and no longer associated
with a specific screen. This change actually makes mode management cleaner
as there is no more per-screen list of modes to deal with.
This changes the RandR 1.2 ABI/API for drivers.
Output options and mode origins both affected driver ABI. memmove mistakes
were causing 'Freeing resource which isn't there' messages.
Prune unused non-user defined modes from available list now.
RandR is getting too big to live in one file; split into one file per object
type (crtc, mode, screen), leaving the rest of the code in randr.c.
Code is slowly approaching the point where it will drop-in as a replacement
for the old 1.0 implementation.
