I've verified in a personal project that this code works. I'd like to get a review of it so we can hopefully get this merged! Going to ping @Jasper-Bekkers, hopefully this isn't too much of a hassle. No rush here just want to make sure you see it! |

I think on other platforms then we should fail with an error rather then silently failing to create an exportable texture.

The error would occur elsewhere, see lines 843-845

Going to ping you @MarijnS95 and @Jasper-Bekkers since this has been stale for a while |

This has been tested by my own project, though no in tree testing is there yet(not sure how I'd add that). Also, the testing is only for vulkan Linux but I suspect it would also work on Windows in its current state.
Based on discussion in #274, also going to ping @Jasper-Bekkers :)
Implementation details: the memory is only allocated with support for exporting it later. The user must manually export the memory later, though this isn't very difficult. Used as a reference was this article from vulkan docs.
