From 80444effc62ac91b127cd7811f84c1689eabd7c8 Mon Sep 17 00:00:00 2001 From: Julian Eisel Date: Mon, 6 Mar 2017 00:40:48 +0100 Subject: Multi-View: Map cursor coordinates to visual coordinates When rendering multi-view in side-by-side or top-bottom mode, we squash the UI to half of its size and draw it twice on screen. That means the cursor coordinates used for UI interaction don't match what's visible on screen. This commit is a little event system hack (tm) to fix this. It has some small glitches with cursor grabbing, but nothing to bad. We'll also use it for viewport HMD support.
