Probably we want to rename the test CheckMusDemoInternalDraws (or alternatively
have it check both internal and external modes).

If internal vs external is decided at compile time then it makes sense to leave
the test at MusDemoTest and it will test the appropriate thing for the platform?
Otherwise, one test fixture MusDemoTest is fine but rename the test case
CheckMusDemoInternalDraws.

Acknowledged.
