* This patch adds multiscreen support to Xephyr. For instance,
the command line : "Xephyr :4 -ac -screen 320x240 -screen 640x480"
will launch with two "screens" - namely two main windows.
The first main window represents a screen that has the number :4.0, with
a geometry of 320x240 pixels, and the second one represents a screen
that has the number :4.1 with a geometry of 640x480.
The command line: "DISPLAY=:4.1 xclock" will launch the xclock program
on the second screen, for intance.
* this patch was edited by Dodji Seketeli <dodji@openedhand.com> for:
- better style compliance with the rest of the Xephyr code
- make sure Xephyr could be launched with no -screen option. By
default that creates a default screen of 640x480 pixel like before
- display full titles on the windows - with insctructions to grab
keyboard and mouse - like before.
Convert KDrive to GPE/GKE interface.
Add first-class drivers and enumerate every device separately through
Xi, instead of lamely attempting to aggregate them.
Add XKB support to the Linux keyboard driver.
Add 'thumb button' support to the tslib driver.
Rejig InitInput, so each DDX has to add a list of drivers it supports.
Support NewInputDeviceRequest, et al.
same width/height for front-buffer drawing. The fakexa code then uses
this extra space for offscreen pixmaps. Note that this tones down the
absurdity of fakexa's offscreen pixmap alignment requirements (odd
alignment is too weird, so stick with "24", which is still strange but
exists out there). It also fixes a couple of bugs in the fakexa
implementation revealed by using offscreen pixmaps.
