Avoid loading current dithering matrix on each mouse move (related to #4174)

Browse Source 
With this change we are reusing the cached/loaded matrix on each
DitheringMatrixInfo struct, calling the
load_dithering_matrix_from_sprite() function just one time (not on
each brush preview/mouse movement).
