Fix handling of negative size request for Bitmaps in LocalImageResolver

Requesting negative sized bitmap should mean "no restrictions" and not "please resize to -1x-1". This fixes the corner case for pure bitmaps.
Also reduce severity of logging when we're falling back to non-ImageDecoder load since that's not a catastrophic failure.
