+Subject: [PATCH 2/3] randr: Consider rotation of slaved crtcs when computing
bounds
+Date: Wed, 23 Jul 2014 12:35:14 +0100
+
+When creating a pixmap to cover a rotated slaved CRTC, we need to
+consider its rotated size as that is the area that it occupies in the
+framebuffer. The slave is then responsible for mapping the copy of the
+framebuffer onto the rotated scanout - which can be the usual RandR
+shadow composite method.
