mpeg2dec is a bad citizen in Stridesville.

Take the following video:

http://lycos.dropcode.net/xgl/xgl-gentoo-lycos.mpeg

which has dimensions of 764x556 pixels, so it gets cropped + copied before
sending it out, albeit the new I420 output buffer is allocated with wrong size,
and strides (as implicit by X) are not taken into account when copying.

This is with up-to-date CVS, ie. including the fix from bug #330844 (which is
required).
