Comment:

 Before, AGGW2DRewriter.cpp needed to flip the height to get the DWF layers
 to render properly.
 When DWF layers are rendered, it calls AGGRenderer's DrawScreenRaster.
 This code was changed in the raster re-projection implementation.

 AGGW2DRewriter's agr_process_image and agr_process_pngGroup4Image do not
 need to flip the height in their calls AGGRenderer::DrawScreenRaster.
