function updateLayout ​

virtual void updateLayout(
    DrawInfo & context
) override

virtual void updateLayout(
    DrawInfo & context
) override

Updates object's m_rect, m_displayRect and any other object size variables.

See: m_rect, m_displayRect

Reimplements: DIWNE::DiwneObject::updateLayout

In other words this method is responsible for keeping track of the objects size.

IMPORTANT: This method should only update the m_rect's size, NOT it's position.

The object's rectangle is often set directly from ImGui's last item rectangle. But ImGui coordinates are aligned to pixel boundries via truncation of the coordinates, if the object's rect was updated directly using the screen space ImGui rectangle, there might be a slight discrepancy in the new position converted back to DIWNE coordinates which would cause the object to drift in a feedback loop.

m_displayRect should be updated together with m_rect to preserve correct pixel-aligned rendering in afterDraw(). TODO: Figure out if m_displayRect.Max should be aligned as well or not

This method is called after end() and before the afterDraw() method which can use the calculated size values for final drawing.
