Follow cl-wl 4f0e504: five more protocols, cursors, pipes and borrowed proxies
Protocol Bindings describes tablet-v2, cursor-shape-v1, text-input-v3,
pointer-constraints-v1 and relative-pointer-v1, and the new Cursors page
cursor-shape-v1 and cursor themes through cl-wl/cursor. The API
Reference adds BORROW-PROXY and the pipes, MAKE-PIPE, RECEIVE-TEXT and
SEND-TEXT, which Requests and Events introduces and a clipboard recipe
uses; it was run against the test compositor. The raw layer, errors,
lifetimes, allocation, the scanner's protocol list, the requirements, the
test count and CI follow.
