Xorg's XIWarpPointer doesn't support multi-head display while
XWarpPointer does.
Revert since this is a known TODO in Xorg and setting a custom
xinput matrix seems not to be used often.
Resolves T50383
Before this Blender always needed the Wintab driver. This adds support for the
native pressure API in Windows 8+, making it possible to get pressure sensitivity
on e.g. Microsoft Surface hardware without any extra drivers.
By default Blender will automatically use Wintab if available, and if not use
Windows Ink instead. There is also a new user preference to explicitly specify
which API to use if automatic detection fails.
Fixes T57869: no pressure sensitivity with Surface pen or laptop.
Code by Christopher Peerman with some tweaks by Brecht Van Lommel.

This disables touch gesture recognition in Blender, avoiding any initial delay
when drawing with grease pencil, texture paint, etc.

Previously we would try to guess what the main tablet device is, but this is
error prone. Now we keep a list of X11 devices and try to match events to
them. On the Blender side there are still some limitations in regards to using
multiple devices at the same time, but this should improve things already.
Fixes T59645.

We use a hidden window for each offscreen context we need.
On X11 (linux) it does not show any other windows in the OS task bar
but it might be the case on other operating systems (untested).
This is no longer needed with the new offscreen draw method, so use whatever
is default and hopefully fastest. Fixes console warnings in some setups that
don't have swap copy.
