Class structure for PangoRenderer.

The following vfuncs take user space coordinates in Pango units and have default implementations:

draw_glyphs
draw_rectangle
draw_error_underline
draw_shape
draw_glyph_item

The default draw_shape implementation draws nothing.

The following vfuncs take device space coordinates as doubles and must be implemented:

draw_trapezoid
draw_glyph
