CC Rotary Control Design

[AlexMitchellMus]

sfizz needs a way of displaying rotary knobs, this is a simple knob design, that shows both a label, ccN, and value.

It can be modified to be a pan (bi-polar), or volume rotary knob.

I may suggest, for easier read, the CC number displays without the leading zeros, so just e.g. CC 7 or CC 35.
For the value's curve, yes it will be great to have Linear (0 to 100%) and Bipolar (-100% to 0 to +100%). If possible, I also suggest to add another one, Inverted Linear (-100% to 0). It can be useful for e.g. offset_onccN control.
For the Bipolar, as it can also be used for other, like tune, it maybe simpler to display it as -100 to 0 to +100%, rather than using L and R letters, for more generic view?

For example, sforzando has the CC 128 as a bipolar value control display

The next question is,
At which level this control type need to be defined?
Is it at player-level (exclusive to sfizz UI)?
Or with opcodes inside the sfz file?

If from the sfz file, maybe new opcodes for it need to be added, like :

<control>
label_cc7=Pan
set_realcc7=0.5
display_cc7=bipolar

display_ccN= can have 3 values :
linear bipolar and inverted

Other opcode name than display, maybe, type_ccN=?

<control>
label_cc7=Pan
set_realcc7=0.5
type_cc7=bipolar

@alcomposer
From the example image, since it going to have the rotary value bar displayed as well, I think we don't need the % sign. So just 0 to 100,
or -100 to +100, etc..

If more precision can be added, maybe having decimal point value will be nice and useful, like 50.2 or 50.28
