Move the 0.5 offset we add for aliased rendering to updateMatrix()
The old code set and unset a temporary matrix for every draw command
when doing aliased rendering. Instead, we just use a flag to indicate
that updateMatrix() should add the offset. This means the offset is
added only once. When doing lots of small rendering operations on a
(non-multisampled) QGLWidget, this gives up to 72% performance boost
on the SGX.
