Patches of Hacker‘s morph

[ghost]

Main modifications:

• Add a Distance channel to the keyframe fixture similar to the circular fixture
• Add Dolly Zoom Modifier
• More curves
• Shader option curves (It will try to patch the shader code, which usually runs pretty consistently, but I guess there are always exceptions, so I added a option to disable it)
• Optimization of some interface operations
• Camera now using eye position
