Presently it is still needed until such time 0N/A * as font configuration files (or the implementation equivalent) can have 0N/A * all references to fonts that are not handled via Java 2D removed. 0N/A * Currently there are two cases where this class is needed, both on 0N/A * Unix, primarily Solaris, but useful on Linux too if fonts have moved. 0N/A * 1. Some legacy F3 fonts are still referenced so that AWT "X/Motif" 0N/A * can get dingbats and symbols from them. This can be dispensed with when 0N/A * either AWT is based on 2D, or when the X font path is known to always 0N/A * contain a Type1 or TrueType font that can be used in font configuration 0N/A * files to replace the F3 fonts. 0N/A * 2. When location of font files by 2D fails, because of some system 0N/A * configuration problem, it is desirable to have a fall back to some 0N/A * functionality that lessens the immediate impact on users. Being able 0N/A * to perform limited operations by using bitmaps from X11 helps here. 0N/A * Verifies native font is accessible. 0N/A * @throws FontFormatException - if the font can't be located. 0N/A /* This is set true if this is an instance of a NativeFont 0N/A * created by some other font, to get native bitmaps. 0N/A * The delegating font will call this font only for "basic" 0N/A * cases - ie non-rotated, uniform scale, monochrome bitmaps. 0N/A * If this is false, then this instance may need to itself 0N/A * delegate to another font for non-basic cases.
