  Font/Pango Text: fixed some weird color precision levels

cairo_set_source_rgba takes color and alpha parameters as 0..1.0 doubles. A fully opaque channel value (255)
was being set as 0.99609375 instead of 1.0, which it should be.

  GUI2/Canvas: handle text alpha as a render-time op

This reduces the number of times the text itself needs to be rendered, especially for areas like the
story viewer where the only difference is alpha.
