d3d12_copy_manager #23
Description
For initial data uploads we need something better than what is currently implemented. What would be desired:
- Implemented outside of the d3d12_device.
- Independent of what frame we're on.
- Thread safe.
- As foolproof synchronization as possible (i.e. fence will automatically be added when a resource is used that has a pending upload)
- Use copy queues.
- Host visible upload memory preferably will not resize. Either upload piece meal, or one shot allocation for large resources.
