core: Fix pixel grid snapping in RenderViewport
Our painting code is assumed to work as following: scale the geometry,
snap it to the pixel grid, apply the render transform, e.g. flip the
geometry vertically.
However, with QMatrix4x4 in RenderViewport, we have a slightly different
order: scale the geometry, apply the render transform, snap to the pixel
grid. It results in mapToRenderTarget() not properly mapping logical
geometry to the device geometry, which later manifests as glitches.
