Parse a single <visual> or <collision> into a LinkGeom. Returns false if it has no recognizable geometry.

Accept the `kind` discriminator; returns false on an unknown kind. Only "transform" is implemented here ("markers" is routed by a different host); the

The app persists its active theme to QSettings("StyleSheet::theme") (Theme.cpp) — the same key the rest of pj_dialog_host (widget_binding.cpp) reads.

Bind an instance method (`calculate`/`reset`) by name WITHOUT triggering any metamethod: first a raw field on the instance, else a raw lookup through

Approximation of arc tangent ( error below 0,005 radians )

Rasterize already-prepared SVG bytes into a px-logical QIcon at size*DPR so it stays crisp on HiDPI. Callers own the theming/recoloring of `svg_data`;

Read a <color rgba="r g b a"/> element into a vec4. Returns nullopt when the element is null or "rgba" fails to parse; default {0.7,0.7,0.7,1.0} lives

Read one column of a topic as doubles (readValues above is column-0 only).

Render one of the app's Material chevron SVGs (keyboard_arrow_left/right), recolored to `color`, into a px*DPR QIcon. The source path's own fill is ir

Replace the heap top with its in-chunk successor (has_next) or drop it. O(1) when the successor is still the global minimum — which is every advance w

row_step = point_step * width, computed in uint64 and clamped to UINT32_MAX so an adversarial width/point_step product cannot silently wrap the uint32

A spread of representative finite values plus +/-inf (callers pre-filter NaN).
