* Add deferred cockpit lighting
* Put deferred Cockpits behind a flag
* (hopefully) fix bad in-case initializer
* clear non base color buffer in subsequent deferred passes
* Proper deferred Cockpit rendering
* undo whitespace changes
This is basically the tutorial from vulkan-tutorial.com adapted to using
VulkanHpp and with some refactorings that extract some locigally
self-contained code.
Currently only draws a simple colored triangle.
This adds the Vulkan code for choosing a physical device, creating a
logical device from that and then initializing a swap chain.
This also contains code for filling out the graphics API pointers with
stub functions so that the API functions can be developed gradually.
These changes allow FSO to "run" with Vulkan but nothing is rendered
yet.
