[Laszlo-dev] Snippets make 2 requests when font tag is present

[Henry Minsky]

There is indeed a weird hack that snippets use when importing a font in
swf8.
The snippets library file executes a ImportAssets2 instruction when it
loads, with a URL pointing to itself, which causes the fonts to show up in
the top level environment.

I don't know why it works, but its the only way we found to load fonts from
a library, at one point.

The end of a snippet contains this code when it is generated

        if (mLibFontsDefined) {
            ImportAssets2 ia = new ImportAssets2();
            //System.err.println("setting ImportAssets url="+this.liburl);
            //get property of base url for fonts to import
            String importFontUrlPath =
LPS.getProperty("import.font.base.url");
            if (importFontUrlPath != null) {
                if (importFontUrlPath.endsWith("/") == false) {
                    importFontUrlPath += "/";
                }
                if (liburl.startsWith("/")) {
                    liburl = liburl.substring(1);
                }
                liburl = importFontUrlPath + liburl;
            }
            ia.setUrl(liburl);


It may no longer be necessary in the current generation of Flash player. But
that is what happens,
the compiler adds a "import" SWF byte code instruction to the file to cause
it to import its own
definitions when it is loaded. The request ought to be cached in the browser
the second time though, but
it looks like it is requesting a different URL than the one that the snippet
loaded from?
