No longer round the non-AA clip bounds
By no longer rounding the non-AA clip bounds we increase the probability that a non-AA clip will be dropped when applied to a non-AA rect draw (particularly at half pixel translations).
To make this work in practice we must also make the clip stack check if the non-AA clip is relevant before we preemptively employ a scissor clip.
Note that I have verified that this removes the gross clipping errors from the Chrome repo case but the rounding to scissor clip behavior could still happen in other cases.
