Use glyph properties instead of renderer state in draw_opaque_box
Use glyph properties instead of renderer state in draw_opaque_box

scale_x, scale_y and hspacing should be read from the GlyphInfo
of the glyph the box is based on, not from render_priv->state.
The values in the renderer state are affected by override tags
specified after this glyph, so they are irrelevant.
