[Have a look at math_inset.h first]
The MathCursor is different from the kind of cursor used in the Outer
-World. It contains a stack of MathCursorPos, each of which is made
+World. It contains a stack of CursorPos, each of which is made
up of a inset pointer, an index and a position offset, marking a path from
this formula's MathHullInset to the current position.
