[LDView] LDView 4.4 Beta 4 test release

[Philippe Hurbain]

For what it's worth, I placed a hold vote on tm02o2000.dat stating that it should be named rm02o2000.dat.

Agreed, primref makes it clear:

This suite of primitives are used to generate circular torus sections. By default all these primitives produce a torus with a major radius of 1LDu, so typically need to be scaled up in the {x} and {z} dimensions. The first character denotes whether the minor radius is smaller than (tff primitives) or larger than the major radius (rff primitives). The latter are termed reverse ratio tori.
