Directly related to https://github.com/gfx-rs/wgpu-rs/issues/324

[hecrj]

You could try the upcoming OpenGL renderer in #354.

Hello @hecrj !

Using feature/glow-renderer branch, it is working ! Nice job. Note, in "tour" example, i can't see image (this is the only bug i can see):

[hecrj]

@buxx Glad it worked!

That's expected, images and SVG are not supported yet in the OpenGL renderer (they will be soon!).
