fixed_pipeline_state: Define structure and loaders The intention behind this hasheable structure is to describe the state of fixed function pipeline state that gets compiled to a single graphics pipeline state object. This is all dynamic state in OpenGL but Vulkan wants it in an immutable state, even if hardware can edit it freely. In this commit the structure is defined in an optimized state (it uses booleans, has paddings and many data entries that can be packed to single integers). This is intentional as an initial implementation that is easier to debug, implement and review. It will be optimized in later stages, or it might change if Vulkan gets more dynamic states.

fixed_pipeline_state: Define structure and loaders The intention behind this hasheable structure is to describe the state of fixed function pipeline state that gets compiled to a single graphics pipeline state object. This is all dynamic state in OpenGL but Vulkan wants it in an immutable state, even if hardware can edit it freely. In this commit the structure is defined in an optimized state (it uses booleans, has paddings and many data entries that can be packed to single integers). This is intentional as an initial implementation that is easier to debug, implement and review. It will be optimized in later stages, or it might change if Vulkan gets more dynamic states.
