to `surfman`. This is a large commit; explanations of each change follow. This adds an optional compute shader path, off by default, for rendering fills to alpha masks. It usually does not improve performance at present, but it provides a good baseline for further optimizations. Later improvements will likely aim to avoid writes to the mask texture entirely. Supporting infrastructure for compute shader has been added to `pathfinder_gpu` for the OpenGL and Metal backends. The Metal backend has been optimized to avoid unneccessary buffer allocations and reflection. As part of this, argument buffers have been removed, as the current SPIRV-Cross compiler no longer requires them. The GPU renderer has been improved to avoid stalls. Now, separate buffers are allocated for each fill batch and for each frame. This can be extended in the future to allow for separate buffers for tile draw operations as well. SDL usage has been removed in favor of the native Rust `surfman` and `winit`. Because `surfman` allows for selection of the integrated GPU on multi-GPU system, it is chosen by default. The demo supports a new `--high-performance-gpu` option to opt into the discrete GPU. |
