libcamera: geometry: Provide in-place versions of the Size helpers
Add alignDownTo(), alignUpTo(), boundTo() and expandTo() helper functions to the Size class. These are in-place versions of the existing alignedDownTo(), alignedUpTo(), boundedTo() and expandedTo() functions. The new helpers return a reference to the size, to allow chaining the functions. One can thus write size.alignDownTo(16, 16).alignUpTo(32, 32) .boundTo({ 40, 80 }).expandTo({ 16, 80 }); instead of size.alignDownTo(16, 16); size.alignUpTo(32, 32); size.boundTo({ 40, 80 }); size.expandTo({ 16, 80 }); Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Jacopo Mondi <jacopo@jmondi.org> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
