Laszlo Agocs 30e27328e3 rhi: Unify handling of special cases for scissor and viewport rects 
With OpenGL a scissor (or viewport) rectangle is not allowed to have a negative
width or height. Everything else is allowed. This is also the semantic we wish to
keep for QRhiViewport and QRhiScissor.

This raises some problems. For instance, when we do bottom-left - top-left
rectangle conversion, the case of partially out of bounds rects needs to be
taken into account.

Otherwise, Qt Quick ends up in wrong scissoring in certain cases, typically when
the QQuickWindow size is decreased so the content does not fit because that will
then start generating negative x, y scissors for clipping (which is perfectly
valid but the QRhi backends need to be able to deal with it)

Then there is the problem of having to clamp width and height carefully, because
some validation layers for some APIs will reject a viewport or scissor with
partially out of bounds rectangles.

To verify all this, add a new manual test, based on the cubemap one. (cubemap was
chosen because that is an ideal test scene as it fills the viewport completely, and
so it is visually straightforward when a scissor rectangle is moving around over it)
