Fix shader toggling logic bug introduced after changing to GetFocusedPane function.
Rename a class for, hopefully, ever-so slightly increased clarity.
Remove a parameter from a yet-unused function.
Draw shadertoy thumbnails using ShaderToyPane's function, requiring a workaround pointer-injecting function.
Add an empty VAO member to ShaderToyPane so we can appease core context without having to load and initialize Pane's shaders once for each instance.
Rip out some obsolete calls to m_shaderToyScene.
Merge branch 'master' of https://github.com/jimbo00000/RiftRay
Add an accessor function to get rid of one reference to m_shaderToyScene.
Add a pointer to keep track of the active ShaderToy in ShaderGalleryScene as well as its pane and draw using the Pane's function.
Remove ShaderToyScene class entirely.
