Support blitting into framebuffer #226

Closed kvark closed 3 years ago

Seeing this warning from Dota2:

Vulkan swapchain does not support VK_IMAGE_USAGE_TRANSFER_DST_BIT. Upscaling desktop friendly fullscreen not supported.

Technically, it we are talking about upscaling, which would be blitting, that's something the backends often implement as render passes anyway. So we could still support it on swapchains.

Should be fixed by #230 minus possible bugs
