Tablet/Touchpad: yes Tablet/Touchscreen: no
A touchscreen should give button press upon touch. If this logic is
allowed to kick in then you get a double tap if user does a single
tap.
Below it was using is_absolute() to prevent. The reason I moved is
really in prep for next patch which moves touchscreen button presses
here. It improves readability to me to remove if() from calling
function.
