* fix: use palette text color for I/Q and HUD text (text was not visible on light themes)
* fix use palette dark color for circle border on light themes (border was barely visible on light themes)
* fix: consider circle border pen width when drawing (circle was cut-off by 1px)
* change: enable antialiasing for drawing the HUD circle

* fix: adds small border around the Waveform to guarantee good contrast regardless of the surrounding background color (was a problem on light themes)
* fix: make axis line color less distracting / lower opacity (now uses same color as used in RGB parade)
* fix: prevent clipping bottom y value
* change: instead of drawing current y value in the HUD scale below/above top/bottom scale values to prevent clipping let's hide the scale value instead and only show the current y value
* change: draw current y value and horizontal line in highlight color instead of text color (think this looks better when drawing the parade only in black/white color mode; same color as used in RGB parade)
* change: use same margin between drawing area and scale on the right for both Waveform and RGB Parade
