rust-windowing/softbuffer

How rust-windowing/softbuffer works

Softbuffer is a cross-platform CPU image presentation library: an application supplies a window/display handle, obtains a writable surface buffer, draws pixels, and presents it. The public API dispatches through a backend interface to platform-specific presentation implementations; the README describes compositor handoff and double buffering. Platform source is only sampled for some backends, so platform-specific internals and compositor links are limited to documented or excerpted relationships.
