This detects and handles also local files (as filenames, or URLs with "file:" protocol).
function OpenDocument(APath: String): Boolean;
Warning: this symbol is deprecated.
Open a local file or directory. You should instead use OpenURL, that automatically detects local filenames and URLs leading to local filenames.

SCannotOpenURL = 'Browser not found on your system.';
If defined, the compiled code will have embedded all the variations of basic fonts for the X3D Text node (see [http://castle-engine.sourceforge.net/x3d_implementation_text.php]). This is comfortable (the FontStyle font works, with 3 * 4 font variations, out of the box), but it increases your exe size — possibly without a reason, if you don't use FontStyle X3D node.
Undefine this to conserve around 0.7 MB in exe size. All the Text X3D nodes will use standard sans non-bold, non-italic font.
