"""Pixel is its own tool, not a brush preset ("brush type").

The 1px hard-square brush used to be exposed as the built-in `pixel-1px`
preset, listed under the flyout's "Brushes" heading. It is now a real tool
(`pixel`) in the brush slot's flyout, next to Brush and Eraser, and the pixel
preset is hidden from the preset list/dropdown.
