Do not draw negative-size ShaderEffect(Source) items.
We were a bit inconsistent here. A negative size Image element would not
render at all, a negative size ShaderEffect would render mirrored
and a negative size ShaderEffectSource would trigger an assert.
Be consistent and not draw any of them.
DropShadow from QtGraphicalEffects uses both a ShaderEffectSource and
a ShaderEffect together, so keeping the behavior in ShaderEffect
would make it render incorrectly.
