- Added SetRenderScale method to both D3D12 and Vulkan backends to adjust the render scale dynamically. - Updated eye size calculations to reflect the new render scale in both backends. - Implemented ResizeWritablePair method to handle resizing of swapchains based on the requested eye sizes. - Modified BeginFrame methods to ensure swapchains are resized appropriately before rendering. - Enhanced error handling to maintain current eye sizes when the requested sizes cannot be allocated. - Added tests to validate render scale functionality, ensuring correct behavior when scaling up and down, including handling of refused sizes.
