Bug 1243538: [webm] P7. Let the decoder handle picture resizing. r=SingingTree

Browse Source 
Is is now up to the decoders to automatically determine the correct size of the decoded frame.
By leaving the original dimensions in the VideoInfo, it will allow automatic rescale of the cropping window according to the original dimensions.
