Seth Hillbrand e8d3b68e6b Cairo: Fix high CPU usage in fallback graphics mode ...

Create wxPaintDC in onPaint() to acknowledge paint events. Without this,
wxWidgets keeps sending paint events because it thinks the window still
needs to be painted. This caused continuous repaints in Cairo mode,
consuming CPU when dialogs with preview canvases were open.

The OpenGL GAL has the same issue but is not affected because
wxGLCanvas handles paint events differently via its double-buffering
mechanism.
