try "SizingMethod" instead of "sizingMethod"

[designerfuzzi]

wrong written filter:progid:DXImageTransform.Microsoft.Matrix(...) could do wrong things!
perhaps thats the bug you try to workaround.

just like dokumented a misstyped command in your filter.
sizingMethod could be better SizingMethod

dokumentation here:

and did you try ? ..
SizingMethod='clip to original'

written with a mac :D
