No option for 1:1 mouse mapping in the settings

[Christian Lanig]

It is impossible to map mouse dots to pixels one by one through the system settings or in other words to disable mouse acceleration at all. Although it is clearly the most intuitive behavior of a cursor.
I was experiencing extremely heavy acceleration by default in 15.10 so my 10.000 DPI mouse was nearly unusable even with 3.000 DPI. This is only acceptable if you are able to change it via GUI.

I wanted to wait to file a bug until Unity8 which I expected to arrive earlier. I hope that such an option might arrive in Unity8 at least.

A temporary workaround was to create a /etc/X11/xorg.conf.d/50-mouse-acceleration.conf in 15.10.
But it's extremely annoying and there is neither guarantee that the settings provided by ArchWiki for example, really lead to a 1:1 mapping. Nor will it work consistently when mouse drivers change and so on.

So finally - such an option belongs to any mouse settings interface in operating systems in general - without any doubt.
