As an alternative to gsk_vulkan_image_new_from_data() that takes a given data and creates an image from it, add a 3 step process: gsk_vulkan_image_new_for_upload() gsk_vulkan_image_map_memory() /* put data into memory */ gsk_vulkan_image_unmap_memory() The benefit of this approach is that it potentially avoids a copy; instead of creating a buffer to pass and writing the data into it before then memcpy()ing it into the image, the data can be written straight into image memory. So far, only the staging buffer upload is implemented. There are also no users, those come in the next commit(s).
