Dirty mockup explaining tablet to respect screen aspect ratio
SUMMARY
Currently, there are 3 options for tablet mapping under Wayland:
Stretch and Fill, Keep aspect ratio and fit, Map to portion
None of them can have a true effect on mapping **tablet itself**, it still need
to adjust manually.
"Keep aspect ratio" map the tablet full aspect ratio to the monitor, but after
resizing tablet area, it doesn't do anything to screen mapping.
"Map to portion" map to a portion of the monitor and have a "Lock aspect
ratio", but it can only lock the ratio of the monitor itself, leaving "tablet"
itself without any ratio lock.
Currently, I have to switch to X11 and enter kcm_wacomtablet setting, click on
"Map to screen proportion" and lock aspect ratio, resize tablet area, copy the
X/Y matrix under setting, then use a calculator to divide the ratio, then put
the result under `kcminputrc`: InputArea=0,0.22297297297,1,0.777027027027
PROPORSAL:
A checkbox to force tablet area keep screen ratio under "Map to portion".
For example, if the screen aspect ratio is 16:9, the tablet area mapping should
be forced in 16:9 when enable the checkbox.
