This is done by * creating a wp_viewport object for the surface and setting the destination * rectangle to the surface size before the scale factor is applied. * * The buffer size is calculated by multiplying the surface size by the * intended scale. * * The wl_surface buffer scale should remain set to 1. * * If a surface has a surface-local size of 100 px by 50 px and wishes to * submit buffers with a scale of 1.5, then a buffer of 150px by 75 px should * be used and the wp_viewport destination rectangle should be 100 px by 50 px. * * For toplevel surfaces, the size is rounded halfway away from zero. The * rounding algorithm for subsurface position and size is not defined. * * @section page_ifaces_fractional_scale_v1 Interfaces * - @subpage page_iface_wp_fractional_scale_manager_v1 - fractional surface scale information * - @subpage page_iface_wp_fractional_scale_v1 - fractional scale interface to a wl_surface * @section page_copyright_fractional_scale_v1 Copyright * <pre> * * Copyright © 2022 Kenny Levinsen * * Permission is hereby granted, free of charge, to any person obtaining a * copy of this software and associated documentation files (the "Software"), * to deal in the Software without restriction, including without limitation * the rights to use, copy, modify, merge, publish, distribute, sublicense, * and/or sell copies of the Software, and to permit persons to whom the * Software is furnished to do so, subject to the following conditions: * * The above copyright notice and this permission notice (including the next * paragraph) shall be included in all copies or substantial portions of the * Software. * * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
