When the mouse cursor is inside the UV face,
extend the selection threshold.
This means when zoomed in, a face can always be selected when the cursor
is inside it.
In the case of multiple overlapping faces - the face with the closest
center is used.
----
Prior to 246efd7286, the UV selection
threshold was scaled by the zoom level, so selecting a face when zoomed
in close would often often select faces even when the on-screen center
was outside the intended threshold.
Having a zoom-independent threshold may require more precision than
users are used to.
This change addresses this.
