Procedurally generate UI control ticks #48

Closed anthonyalfimov closed 3 years ago

anthonyalfimov commented 3 years ago

Currently, the ticks around knobs are part of the raster image, and they don't always correspond to actual parameter values. Replace them with procedurally drawn ticks that do represent meaningful parameter values.

Consider adding labels as well (2 - 3 labels, beginning and end of range, plus mid-point?).

We will need to determine the angular range of the knob image asset to place the ticks. Alternatively, we could switch to procedurally draw the "pointer mark" of the knob as well. This would reduce our reliance on raster assets and allow to use a single knob image instead of a strip.

Tick generation implemented.

TODO:

[x] Pick / generate reasonable list of minor ticks for all parameters. In some cases skew factor might have to be adjusted.
[x] Tune the tick look. Colour, length, thickness, dashes or continued under the knob.
[x] Procedurally draw the "pointer mark" of the knob.
[x] Add tick and "pointer mark" inner shadow
