There was a problem hiding this comment.
There comes a point where a struct is preferred over N return values 😃. I suggest declaring a FramebufferAttachmentInfo struct in this file with Width, Height, Index, Format and CanResize fields.

This does 2 things, first it allows us to copy out an image from a Vulkan compute queue.
Secondly it allows us to choose to not resize the images in the server. This is primarily so that the client can resample how it chooses rather than forcing us to do a software resize in GAPIS.
