integration of swap x/y settings in touchscreen plugin

Hi There,
Because Volumio2 is diferent from raspbian, there is less tuning for the touchscreen and it’s very complicated to swap x an y axes :astonished:(
Have a prefs for swaping/invert X and/or Y directly in the Touch Display Plugin will be a realy cool thing to permit easy touchscreen adaption.
Is it possible ?
