X11: Fix drawing of sliders with gtk+ scheme and GUI scaling >= 2 that left footprints when moved.

Browse Source 
The fix is to use the X11 graphics driver's line_delta_ private member variable also when drawing complex
shapes with fl_begin_loop(). The gtk+ scheme does use fl_begin_loop() to draw its frames.
