- The glium example was upgraded as well and works.
- The wgpu example was not yet touched in this commit, it will
require a version of imgui-wgpu that points to imgui-rs 0.7.0
as well to work.
Due to the yanking of imgui-winit-support 0.6.1, builds that did
not have a lock file started failing in places. I've now locked
the versions of imgui and friends to exactly 0.6.0 to avert those
issues for the time being, with the longer-term fix being the
upgrade of all those to 0.7.0 in #13.
