// used in a command buffer before a dispatch call is issued. As both dynamic scissor and viewport are basic requirements for
// the engine to not bake this state into the PSO, the only known way to fix this issue is to reset the command buffer entirely.
//
// As the render graph has no built in limitations of whether it'll issue compute work before anything needs to draw on the
// frame, and there's no guarantee that compute work will never be dependent on rasterization in the future, this workaround
// will end recording on the current command buffer any time a compute list is encountered after a draw list was executed.
// A new command buffer will be created afterwards and the appropriate synchronization primitives will be inserted.
//
// Executing this workaround has the added cost of synchronization between all the command buffers that are created as well as
// all the individual submissions. This performance hit is accepted for the sake of being able to support these devices without
// limiting the design of the renderer.
