VulkanRenderer using ash 0.38 + winit:
- Instance with KHR_surface + xlib + wayland extensions
- Physical device selection (first GPU with graphics+present)
- Swapchain (FIFO present mode, B8G8R8A8_UNORM)
- Render pass with color attachment
- Graphics pipeline with instanced rendering:
- Vertex buffer: unit quad (4 verts, 6 indices)
- Instance buffer: 8000 CellInstance structs (32 bytes each)
- 2 vertex bindings: per-vertex (quad pos) + per-instance (grid pos,
atlas UV, fg/bg colors)
- Push constants: screen size + cell size
- Glyph atlas: R8_UNORM texture, uploaded via staging buffer
- fontdue rasterizes DejaVu Sans Mono at startup
- Linear filtering sampler
- Descriptor set: combined image sampler for atlas
- 2 frames in flight with semaphores + fences
- Persistent mapped instance buffer (zero-copy per frame)
Shaders (pre-compiled SPIR-V):
- cell.vert: positions quad from instance data, maps to clip space
- cell.frag: samples atlas alpha, blends fg/bg
--mode vulkan: tries Vulkan, falls back to softbuffer window mode
