sw: add rendering for semi-transparent text
I considered passing the text color's alpha value down to the various
vcl backends, but this would need changes everywhere (cairo, opengl, pdf
export, etc). It's much easier to go via DrawTransparent(), that's how
semi-transparent text in Draw/Impress already works.
