David Robillard 60454cc8dc Split pretty much the entire GUI in 3. Audio and Midi "editor strips" and
associated stuff are now separated (with common things in base classes).

Extremely dirty and in progress, but builds, runs, and audio/midi tracks/busses
all look (and really are) distinct in the GUI.

* Base Abstact Class for TimeAxis views that operate purely within the visual domain.

* This class provides many of the common methods required for visual TimeAxis views. The aim is
* to provide an abstract layer during the developmnt of the visual based time axis'. Many of these
* methods have a better home further up the class heirarchy, and in fact some are replication of
* methods found within RouteUI. This, however, has been required due to various problems with previous
* versions of g++, mainly 2.95, which are not correctly handling virtual methods, virtual base classes,
* and virtual methods when used with Multiple Inheritance. Perhaps these could be combined once the
* compilers all agree on hos do to do stuff...
