+// It reads PNG data from name_png static byte arrays that can be created using
+// e.g. misc/scripts/png2c.py.
+//
+// This macro exists mostly as a helper for wxBITMAP_PNG() below but also
+// because it's slightly more convenient to use than NewFromPNGData() directly.

+//
+// Under Windows they should be embedded into the resource file using RT_RCDATA
+// resource type and under OS X the PNG file with the specified name must be
+// available in the resource subdirectory of the bundle. Elsewhere, this is
+// exactly the same thing as wxBITMAP_PNG_FROM_DATA() described above.
