Berthold Stoeger 210660d057 profile: rewrite ProfileScene::pointOnProfile()
This function was used to check wether a screen-point
is located on the profile. Bizzarely, this was done by
transforming into local coordinates and checking
min/max value. Simply check the screen coordinates
directly. Moreover, make the function return whether
the point is inside the region, not outside the region,
to make logic more straight forward.
