+other primitive types.  This key is implemented in the development code.
 
+The next step is to create Kst?Matrix classes which behave as close as
+possible to the same way Kst?Vector does, with an interface as close as
+possible to that of Kst?Vector.  Once this is done, the KstDataSource
+interface can be extended to support loading them (as well as all other
+primitive types).  The Matrix dialog will become an equivalent to the
+Vector dialog.
+
+Note that Matrix needs to be a primitive type internally too.  It should
+not use KstVector.
+
+After matrices are renovated, KstImage needs to be converted into a
+KstBaseCurve and adjusted somewhat to be a generic curve with a matrix
+for storing data.  It is desired at some point to be able to render all
+sort of different image formats easily with this class.  This change,
+however, depends on changes to Kst2DPlot to an extent, and should wait
+for those changes.  (they are minor)
