Looks good to me.

c being 0 implies that either the height or stride were 0, which means
the second to last arg of the call to xcb_render_add_glyphs and final
arg of the XRenderAddGlyphs call will be zero as well in this case.
Looking at XRenderAddGlyphs's implementation this seems not to be
worrisome.  Can't tell offhand what xcb is doing but trust it can handle
