core: Add OutputTransform::map(QRect,Size) overloads These can be useful in case a QRect needs to be mapped. One could convert the QRect into a QRectF and then back to QRect, but given that these conversion helpers are present in rendering hot paths, it would be great to be more efficient and also potentially loosing precision because of floating point arithmetic.

core: Add OutputTransform::FlipY convenience aliases `flip-y | rotate-N` transforms are equivalent to `flip-x | rotate-N`. However, it is not intuitive to express transforms that flip the y axis via flip-x transforms. This change adds convenience aliases to improve code readability and keep code intuitive, which is going to be needed in order to drop TextureTransforms flags.

core: Add OutputTransform::FlipY convenience aliases `flip-y | rotate-N` transforms are equivalent to `flip-x | rotate-N`. However, it is not intuitive to express transforms that flip the y axis via flip-x transforms. This change adds convenience aliases to improve code readability and keep code intuitive, which is going to be needed in order to drop TextureTransforms flags.
