app: in GimpPaintbrush, reuse existing paint buffer 

In GimpPaintbrush, avoid refilling the paint buffer at each dab if
the paint color/pixmap hasn't changed, as gimp_paint_core_paste()
no longer modifies the buffer since the commit before last.

Additionally, fix color-from-gradient dynamics when the image has a
profile.
