Browse source 
2008-10-31  Michael Natterer  <mitch@gimp.org>

	* app/tools/gimpdrawtool.[ch]: add gimp_draw_tool_draw_text_cursor()
	which draws a properly transformed cursor that always has the same
	line width.

	* app/tools/gimptexttool.c (gimp_text_tool_draw): use it instead
	of drawing a cursor here that is broken at anything but 1:1 zoom.
