2008-03-05 Michael Natterer <mitch@gimp.org> * app/display/gimpdisplayshell.h: changed PROJ_ROUND() macros to use RINT() so they work correctly with negative numbers. * app/tools/gimpdrawtool.c (gimp_draw_tool_draw_line) (gimp_draw_tool_draw_dashed_line) (gimp_draw_tool_draw_rectangle) (gimp_draw_tool_draw_arc) (gimp_draw_tool_draw_boundary): use floating-point coordinate transform functions again. These functions were changed to use integer transform functions in 2004 (!!) which broke sub-pixel precision drawing for stuff like straight-line and blend tool and also sub-pixel drawing of the brush outline. Should be backported to 2.4 after it has shown no ill effects in trunk. svn path=/trunk/; revision=25036
