* @param gl the current GL context object. It's read drawable is being used as the pixel source
* and to gather some details which will end up in the filename.
* @param readBufferUtil the {@link GLReadBufferUtil} to be used to read the pixels for the
* screenshot.
* @param fileSuffix Optional file suffix without a <i>dot</i> defining the file type, i.e. <code>
* "png"</code>. If <code>null</code> the <code>"png"</code> as defined in {@link
* TextureIO#PNG} is being used.
* @param destPath Optional platform dependent file path. It shall use {@link File#separatorChar}
* as is directory separator. It shall not end with a directory separator, {@link
* File#separatorChar}. If <code>null</code> the current working directory is being used.
