2003-07-14 Michael Natterer <mitch@gimp.org> * app/paint/gimperaseroptions.[ch]: removed "gboolean hard" member/property... * app/paint/gimppaintoptions.[ch]: ...and added it here. Added gimp_paint_options_get_brush_mode() utility function. * app/paint/gimpairbrush.c * app/paint/gimpclone.c * app/paint/gimpconvolve.c * app/paint/gimpdodgeburn.c * app/paint/gimperaser.c * app/paint/gimppaintbrush.c * app/paint/gimppaintcore.h * app/paint/gimppencil.c * app/paint/gimpsmudge.c: use the new utility funtion where appropriate. Removed trailing whitespace. * app/tools/gimpdrawtool.[ch] (gimp_paint_tool_draw_boundary): changed offset parameters from gint to gdouble so we can show the brush preview at sub-pixel positions. * app/tools/gimppainttool.c: use sub-pixel coordinates for the brush preview if paint_options->hard is FALSE (doesn't work for the pencil yet). The new brush preview unveiled that the positioning of even-sized brushes if off by 0.5 for soft brush application mode and off by 1.0 for hard application mode: * app/paint/gimppaintcore.[ch] (gimp_paint_core_subsample_mask): offset painting by 0.5 pixels on the brushes' even sized axes by shuffling the subsample matrices around. Added "subsampling" for HARD brush application mode since a pixel of an even sized brush can snap to up to four different image pixels depending on the sub-pixel coordinates of the stroke.
