drmkit-csd
Client-side window decorations.
Title bars, shadows, rounded corners and the buttons on them, drawn by the client rather than by a compositor, which is what makes them client-side.
Drawing is CPU work over a pixel buffer. The one part that touches a DRM
device is Surface, which allocates, maps and exports the dumb buffer a
decoration is drawn into. The presenters only compute the property writes
that put those pixels on screen; committing them is the caller's business.
Part of drmkit, a Rust port of drm-cxx. API documentation is on docs.rs.
