Fl_Tree +/- buttons are no longer drawn using bitmaps, different default line color (#995)
Fl_Tree changed to support system color themes (PR #995) merging CyprinusCarpio's mods carried over from from issue #972. * Fl_Tree: use named (colormap) colors to support system color themes (see issue #972). changed connectorcolor() default from gray ramp color to FL_INACTIVE_COLOR (Fl_Color(8)), and similar named colormap colors for icon drawing. * Fl_Tree ⊞ / ⊟ icons (and on macs, ▶ / ▼icons) are now drawn w/fl_draw() functions instead of with xpm bitmaps for colormap control --------- Co-authored-by: Greg Ercolano <erco@seriss.com>
