Move TransformationMatrix and TransformState to LayoutUnits.

[Levi Weintraub]

We want to preserve the added precision we'll get in the render tree when switching to FractionalLayoutUnits through transformations. To this end, I propose moving TransformationMatrix and TransformState to operate on LayoutUnits instead of integers.

[Simon Fraser (smfr)]

I assume you mean mapRect() and clampedBoundsOfProjectedQuad() in TransformationMatrix (the rest is in doubles).

TransformState has no use of IntRect so I'm confused there. You mean HitTestingTransformState?

I've found the build issue with this. I'll upload a fixed patch once this goes through the remaining EWS bots.

Bug in check-webkit-style.  I bet it thinks 'y' is a substring of LayoutUnit.
