- Added an anti-aliasing option to smooth some of the jagged edges.

- Some more minor cleanup work.
- Lower/Upper bounds changed to linked sliders.

- Made 'Smooth Curve' it's own option, separate from bar count.
- Removed the 'Simulate Audio' option to help make the shader more manageable.
- Renamed the 'Bounds' options to hopefully make their effect more clear.
- Added the shapes 'Center L/R' and 'Center U/D'.

Low frequency sounds shouldn't affect the high-frequency bars as much now.

Added support for spacing between the bars.

- Minor shader code cleanup now that the preprocessor supports more logical operators.

- No longer doubles the opacity when stereo bars overlap.

- Fixed an issue causing a seam in the bars even when they were smooth.
- Replaced "Offset" with "Bar Bounds" which lets you adjust how high the bars will be at zero and at 'max' volume.

Enabled 'subtract' transparency mode.
