+    Convert pixel values of the current toolkit to DPI-independent pixel values.
+
+    A DPI-independent pixel is just a pixel at the standard 96 DPI
+    resolution. To keep the same physical size at higher resolution, the
+    physical pixel value must be scaled by GetContentScaleFactor() but this
+    scaling may be already done by the underlying toolkit (GTK+, Cocoa,
+    ...) automatically. This method performs the conversion only if it is
+    not already done by the lower level toolkit, For example, you may
+    want to use this to store window sizes and positions so that they
+    can be re-used regardless of the display DPI:
+    @code
+    wxPoint pt(ToDIP(GetPosition()));
+    wxSize size(ToDIP(GetSize()));
+    @endcode
+
+    Also note that if either component of @a sz has the special value of
+    -1, it is returned unchanged independently of the current DPI, to
+    preserve the special value of -1 in wxWidgets API (it is often used to
+    mean "unspecified").

+
