Features: - Debug-only tracking of objects by type. See get_driver_allocs_by_object_type et al. - Debug-only Breadcrumb info for debugging GPU crashes and device lost - Performance report per frame from get_perf_report - Some VMA calls had to be modified in order to insert the necessary memory callbacks Functionality marked as "debug-only" is only available in debug or dev builds. Misc fixes: - Early break optimization in RenderingDevice::uniform_set_create ============================ The work was performed by collaboration of TheForge and Google. I am merely splitting it up into smaller PRs and cleaning it up. |

Metal Rendering Device
This document aims to describe the Metal rendering device implementation in Godot.
Future work / ideas
- Use placement heaps
- Explicit hazard tracking
- MetalFX upscaling support?
