Graphics TODO list

• Get persp() and friends to return a transformation matrix so that users can annotate 3d plots.
• Get persp() and friends to take notice of par() args passed down in the ... argument.
• Get vector font text justification to work properly.
• Implement vector fonts in mtext() and title().
• Make sure that text expressions, and vector fonts can be used in all text plotting functions; text(), mtext(), axis(), persp() ...
• Add double-buffering to graphics devices.
• Implement lwd=0 a la S-Plus (i.e., the narrowest line width that the device can manage)
• Allow text adjustment for mathematical annotations which is relative to a text baseline (in addition to the current situation where adjustment is relative to the bounding box).
