* get rid of vertex buffers in example

* get rid of unused attributes in example shader

* use negative viewport height to match wgpu

* remove depth buffer

* use SRGB surface

* improve tonemapping

remove 'gamma correction' in favor of hardware srgb support

* make clippy happy

* move tonemapping out of sky(), rename gl_pos to builtin_pos

* rename shaders and use sky shader in wgpu example runner

* apply srgb OETF and invert clip space for cpu example runner

* restructure example directory structure according to #170

* update winit in wgpu example runner

* fix deny.toml example crate refs

* fix ci example name on maOS
