GNOME 3.18 - GTK3 Now Supports RandR 1.5

RandR 1.5 was firmed up a few days ago for X.Org Server 1.18. The lead features to RandR 1.5 are monitor objects and tile support.

X.Org developer at Red Hat, David Airlie, has added the RandR 1.5 monitor support to the GTK3 tool-kit's X11 backend.

The commit explains, "This patch introduces support for using the newly introduced monitor objects in the XRandR protocol. These objects are meant to be used to denote a set of rectangles representing a logical monitor, and are used to hide details like monitor tiling and virtual GPU outputs. This uses the new objects instead of crtc/outputs objects when they are available to create the monitor lists."
