David Edmundson bcd9f1e958 Provide SurfaceItem::shape as a floating vector
Our logical co-ordinates for shape can be floating. The shape is used to
determine final vertices on screen.

The commit appears to introduce some new loops but they're mostly what
QRegion would be doing internally so it shouldn't impact performance.
For most cases we just have a single rectangle in our shape anyway.

opaqueRegion is unchanged for now.
