VkWayland renders weston-terminal.
Replace GLFW on LINUX with proper alternative
Related to #3
GLFW: System choice, wayland VS X11.
On unix GLFW has two variations chosen at compile time... So I don't think it's proper to include it as part of another application.
Modular fbcon support.
I've started working on a rewrite that focuses on implementing support for multiple builds.
- GLFW build that uses imgui to draw window decorations. This is the main focus currently.
- GLFW build that uses a theme-able lua language to draw window decorations, manage window switching, ect. This will likely not work for some time... if at all.
- Linux fbcon, with imgui.
- Linux fbcon, with lua.
Not only is surface creation/management different but input handling also needs to be modular. The API for input should be a message queue containing libinput biased messages. GLFW input handlers should post messages after converting then to a format that more closely resembles libinput events.

This is my first time using cpp and my first time using cmake. I actively use free software and don't have access to windows or binary video drivers.

Vulkan lacks functionality to support Wayland shm pools.

I've got vkwayland to the point where it's receiving image data from my test client weston-terminal. The data comes across as part of a shm pool FD, called a buffer. From what I can tell Vulkan is only able to work with an entier FD, exported from Vulkan... It needs the FD to represent a VkMemory object, not collection"s" of raw image data.
I've asked on IRC about extending Linux to support shm FDs as sources of image buffers from the drm/mesa team, but I doubt it'll be implemented unless there is significant proof that this is a bottleneck. I wonder if anyone saw it, I'll post something on the mailing list if I don't get a reply.
I'll look to see if I can find an ogl/vulkan wayland client to test with, where dmabuf would be used.
Here is a trace from the client.

The drawing bits are everything from [email protected]_region(new id wl_region@18) to the end, surface.commit() is the command the dispatches the drawing of the surface.attack(buffer).
Create buffer means: at offset 0 bytes, width 806, height 491, each row is 3224 bytes, format 0(ARGB8888).
