From 7868654ff7fe5e4a2eeae2b277644fa884a5031e Mon Sep 17 00:00:00 2001 From: Owen Smith Date: Mon, 3 Jul 2017 12:57:53 +0000 Subject: [PATCH] kbdif: Define "feature-raw-pointer" and "request-raw-pointer" Backends set "feature-raw-pointer" if its capable of reporting absolute positions without scaling the coordinates to screen size. This should be set during the backend init. Frontends set "request-raw-pointer" to request that backends do not rescale absolute coordinates to screen size, and the coordinates remain in the range [0, 0x7fff]. This request is only applicable if "request-abs-pointer" is also set. Frontends should set this value before setting Connected.
