To recreate a swapchain now requires making a new SwapchainBuilder or
keeping the old one around. Removed the recreate function since its
purpose was unclear. Introduced set_old_swapchain to allow recyling the
old swapchain. Updated documentation and getting started guide.
Updated the documentation for using the new <error_code> based errors.
Also fixed an issue where SystemInfo wouldn't check if layers had a
debug_utils extension.
Added device::get_queue_families() to facilitate custom queue setups
get_swapchain_images() renamed to get_image(), made member function to
swapchain.
get_swapchain_image_views() renamed to get_image_views(), also moved to
member function of swapchain
fixed bug with headless instance not being correct
Stopped Catch2 from polluting the buildable targets
SystemInfo will be the way for users to know what is and isn't available on their system.
Currently, it only has booleans for if validation layers and debug messenger are available,
but more could be added in the future.
Premise is to let the easy creation of a compute or transfer queue.
If the user supplies a custom list they want to use, defer to that.
Else, enable the basic requirements and be on your merry way.
