Bill Currie aac6fca2c5 [vulkan] Pass a data parameter to QFV_RunRenderPass
The parameter will be passed on to the pipeline tasks in their task
context, allowing for communication between the subsystem calling
QFV_RunRenderPass and the pipeline tasks (for the case of lighting,
passing the current matrix base index).
