[Bf-committers] Camera motion blur bug + fix

[Vidar Madsen]

Hi.

I was trying to achieve a "zoom blur" effect by animating the Lens IPO
of the camera, but it seems the camera properies are only calculated
prior to the separate mblur renders.

Test here: http://vidar.gimp.org/tmp/zoomtest.blend

This tiny patch should fix the (admittedly also small) problem:
