Demonstrate wxRenderer::DrawItemText() alignment in render sample

Browse Source 
This is intended for wxMSW to show differences between themed text
drawing (with wxRendererXP::DrawItemText() under Vista+) and
wxRendererGeneric::DrawItemText(). Use existing option to switch between
generic and native renderer (Ctrl-G) in the render sample to observe
the differences.
