Mirror of snaporca-cad f3b665b. DesignCanvas had ~38 call-sites doing `set_as_dirty(); render()` directly, tagged "llvmpipe: force repaint" — software-GL workarounds from the headless :10 test box. On hardware GL this bypasses the dirty/refresh cycle and burns frames outside the paint event. Funnel all 38 through a new request_repaint() helper that branches on the cached GL renderer string: hardware GL gets set_as_dirty()+wxGLCanvas::Refresh() (render() runs inside the paint cycle), software GL keeps the direct render(), undetected backend takes the safe direct path. Behaviour on the llvmpipe :10 box is byte-identical; hardware GL invalidates the canonical editor way.
