Extend touchscreen_parse_properties() with support for the touchscreen-inverted-x/y and touchscreen-swapped-x-y properties and add touchscreen_set_mt_pos() and touchscreen_report_pos() helper functions for storing coordinates into a input_mt_pos struct, or directly reporting them, taking these properties into account. This commit also modifies the existing callers of touchscreen_parse_properties() to pass in NULL for the new third argument, keeping the existing behavior.
