When opening a single point in map view, the area of interest too zoomed in.

No background is available at that level.
Suggestion, default zoom level of highest available wms zoomlevel.

Fixed in 0deeee3d (branch refactor_linux_gui).

A single-point / zero-area extent had no natural zoom-to-extent, so SetROI/SanitizeRoi expanded it to ViewPortMinSize (~10 m on a WGS84 layer), zooming in past any available background tiles.

Implementation:

• WmsLayer::ZoomToFinestLevel() sizes the ROI to the deepest available tile matrix (m_TMS.size()-1) via Zoom1To1, centered on the current ROI center — i.e. the highest available WMS zoom level, as suggested.
• ViewPort::ZoomToTargetRoi() is a new zoom-to-extent choke point: a normal extent zooms as before; a degenerate one snaps to a background WMS layer's finest level when one is present, else falls back to a fixed default extent (DEFAULT_POINT_VIEW_SIZE_IN_METERS = 1000 m / metres-per-unit, overridable per CRS via a ViewPortDefaultSize sub-item).
• ZoomWorldFullRect, AL_ZoomAll and AL_ZoomSel route through it, so a single point no longer over-zooms whether opened, zoomed-to, or selected.

Verified on a WGS84 layer with a WMS background: opening a single point now lands at the deepest tile level (background visible) instead of the ~10 m over-zoom.
