Peter Hutterer 5cc2c96f82 dix: pre-scale x by the screen:device:resolution ratio 
commit 61a99aff9d
    dix: pre-scale relative events from abs devices to desktop ratio (#31636)

added pre-scaling of relative coordinates coming from absolute devices to
undo uneven scaling based on the screen dimensions.

Devices have their own device width/height ratio as well (in a specific
resolution) and this must be applied for relative devices as well to avoid
scaling of the relative events into the device's ratio.

e.g. a Wacom Intuos4 6x9 is in 16:10 format with equal horiz/vert
resolution (dpi). A movement by 1000/1000 coordinates is a perfect diagonal
on the tablet and must be reflected as such on the screen.

However, we map the relative device-coordinate events to absolute screen
coordinates based on the axis ranges. This results in an effective scaling
of 1000/(1000 * 1.6) and thus an uneven x/y axis movement - the y
axis is always faster.

So we need to pre-scale not only by the desktop dimenstions but also by the
device width/height ratio _and_ the resolution ratio.

					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.

For a comprehensive overview of X Server and X Window System, consult the
following article:

All questions regarding this software should be directed at the
