Render the selection specified by selection for page into pixbuf. The selection will be rendered at scale, using glyph_color for the glyphs and background_color for the selection background.

If non-NULL, old_selection specifies the selection that is already rendered in pixbuf, in which case this function will (some day) only render the changed part of the selection.

page : the PopplerPage for which to render selection
scale : scale specified as pixels per point
rotation : rotate the document by the specified degree
pixbuf : pixbuf to render to
selection : start and end point of selection as a rectangle
old_selection : previous selection
style : a PopplerSelectionStyle
glyph_color : color to use for drawing glyphs
background_color : color to use for the selection background
