  physical monitor DPI.
* 3-Point Screen Angle Protractor & Canvas: interactive transparent 360-degree
  on-screen protractor and measurement canvas to compute exact vertex angles,
  supplementary angles, arm lengths, slope percentages, and bounding-box
  aspect ratios over live desktop snapshots or loaded images.

  magnifier with RGB, HEX, HSL, and CMYK readouts, clipboard copy shortcuts,
