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 is an effort to be able to use the same GLSL code for both Vulkan
and OpenGL. This is done by first compiling the Vulkan GLSL code to
SPIR-V and then using a custom tool (which uses SPIRV-Cross) to convert
that back into GLSL 1.50 compatible code.
The required tool will be downloaded by CMake when glslc is found in the
path. This is included in the Vulkan SDK. To avoid having a hard
dependency on this, the generated files are included in the VCS and are
only regenerated when glslc is found on the system.
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.
This adds a new graphics type for the Vulkan graphics API. All this does
is to create a vulkan instance and a presentation surface with the help
of SDL.
