  rotate around an axis? (Message 1 to 3 of 3)

Hi.
I'm probably missing something obvious.

I have an object, and a vector representing an axis.
I want to rotate the object by n degrees around that
axis. I know about vaxis_rotate for points, and I know
that rotate takes a vector of 3 angles to rotate about,
but beyond that I'm stuck.

I'll keep hammering at it by myself for now :-)

  Axis_Rotate_Trans() in transforms.inc (see the section 7.19 of the
documentation for more info).
