Correct the bug in the translate animation where the offset was part of the
multiplication. It now behaves like all other animations:
out = (prop * factor) + offset

I feel strongly that the existing is wrong and must be corrected - it is non-op
if the offset is zero as I have found to my cost! It is just a typo I expect.

The diff also provides non-op default values for the scale animation.

I've also included Harald's latest eye-candy animation which allows us to
have a very smart heat-haze for exhausts. They have been tested by me and
others on Linux and Cygwin. You might like to upload these - I have a
revised Hunter ready to go as soon as they are uploaded.
