+The ConTeXt figure inclusion mechanisms are among the oldest code
+in ConTeXt and evolve dinto a complex whole. One reason is that we
+deal with backend in an abstract way. What complicates matters is
+that we deal with internal graphics as well: TeX code, MetaPost code,
+etc. Later on figure databases were introduced, which resulted in
+a plug in model for locating images. On top of that runs a conversion
+mechanism (with caching) and resource logging.
+
+Porting that to Lua is not that trivial because quite some
+status information is kept between al these stages. Of course, image
+reuse also has some price, and so I decided to implement the graphics
+inclusion in several layers: detection, loading, inclusion, etc.
+
+Object sharing and scaling can happen at each stage, depending on the
+way the resource is dealt with.
+
+The TeX-Lua mix is suboptimal. This has to do with the fact that we cannot
+run TeX code from within Lua. Some more functionality will move to Lua.
