Fix bug with xaos interpolation, by setting all xaos values to zero first.

Browse Source 
Remove unnecessary resize() in Interpolate().

These are from Simon Detheridge's PR:

Set file name padding in EmberRender and
EmberAnimate based on the log10() of how many images are getting rendered, rather than hardcoding it to 5.

Use non-locale-imbued stream for writing filename in EmberAnimate.

Properly cast immediate float value used with pow() in density filter kernel.
