Function icon_button

src/host/ui/panels/icon_button.h:39–54

Qt-parity icon button: fixed 26px square by default (the legacy Qt frontend's QToolButtons were fixed width 26; see tag legacy-qt), fontello glyph as label. `checked` (when non-null) renders the button in the active color, mirroring a checked QToolButton. `size` lets in-row callers match a neighboring widget's height (e.g. the AC editor's reset buttons beside its input fields).
