* app/text/gimptextlayout-render.c: remove private function which creates the transform matrix. * app/text/gimptextlayout.[ch]: add it here as public API. Also add function which transform and untransform PangoRectangles, points and distances using the transform matrix. * app/tools/gimptexttool.c: convert coordinates using above new transform functions when drawing selection and cursor, and when processing mouse events.
