    	* 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.
