Thibault Saunier 5720ae4f25 framepositioner: Fix some source repositionning rounding issues
Avoid loosing (too much) precision when rescaling back and forth by
storing values in gdoubles.

Handle the fact that position values can be negative

Also fix debug category static variable
as it clashes with the instance variable name in a few methods.
