Draws text

Fills the destination rectangle with the background pixel from gc, then paints the text with the foreground pixel from gc. The upper-left corner of the filled rectangle is at [x, y - font-ascent]. The width is overall-width, the height is font-ascent + font-descent. The overall-width, font-ascent and font-descent are as returned by xcb_query_text_extents (TODO).

Note that using X core fonts is deprecated (but still supported) in favor of client-side rendering using Xft.
