Detailed Description

Vulkan graphics pipeline wrapper.

Handles the complex graphics pipeline state machine. Unlike compute pipelines, graphics pipelines require extensive fixed-function configuration.

Responsibilities:

• Create graphics pipeline from config
• Manage pipeline layout
• Bind pipeline to command buffer
• Bind vertex/index buffers
• Bind descriptor sets
• Push constants
• Dynamic state updates (viewport, scissor, etc.)
• Draw commands

Thread Safety:

• NOT thread-safe
• Create on main thread, use on render thread
