Add BOOST, 3D depth, and gradient-angle knobs

- BOOST: global display level multiplier (0.75 - 2.5, 1.0 default)
- 3D: pseudo-3D bevel/shading on bars, LEDs, peaks and curve (0 = flat)
- G-ANG: 3D gradient angle (-180 - 180, 0 = top-lit)
- Apply CURVING rounded corners to bars and peaks in BAR mode
