[Bf-committers] Feedback on macro design

[joe]

There's a few issues with macros I think need to be solved:

* You can't combine a modal operator with other ones, e.g. a special
select tool that calls another tool afterwards.  For example,
  edge ring select (with preview) and subdivide to create loopcut.
Note that edge ring select isn't a modal tool from the users
  point of view, but it is a modal operator (to draw the preview while
the mouse button is held down).

* You need to be able to set properties in components of a macro
operator at macro definition time.  This is important for extrude,
   for e.g. properly calling normal grab after the extrude, instead of
just grab.
