GLSL ShaderGen: time_float and frame_float do not have any effect

Related to #1951

I believe the attached file should have some animation based on application time, however it just stays still in MaterialXWebViewer.
marbleTime.mtlx.zip

Edit: in some applications the time nodes show up as not connected, this one here should work:
myFile2.mtlx.zip

There is no "play" functionality here nor in the desktop viewer. For the hardware case the u_frame shader uniform needs to be updated and bound as mentioned here

Please consider it a feature request :)

Thanks for this feature request, @hybridherbst, and I've just updated the title to clarify that this feature is missing in our GLSL shader generation, which both the Viewer and Graph Editor leverage for rendering

[hybridherbst]

Thanks @jstone-lucasfilm! I think in addition to the shader generation, the host application also needs to updates the uniforms, right?

[jstone-lucasfilm]

Good point, @hybridherbst, and indeed those updates should be made to the Viewer and Graph Editor when this feature is added.
