note 13029 deleted from function.imagewbmp by felipe

Note Submitter: flapper at redcube dot nl ---- There is a hidden third parameter in the ImageWbmp function that serves as a threshold-holder. When using the function as in: ImageWbmp ($im, "test.wbmp"); it generates a warning: Warning: imagewbmp: invalid threshold value '-1'. It must be between 0 and 255 in blablabla It does generate the image though but for a WML app. it cannot be used since the warning is laden with HTML-tags. To prevent the warning use the following example: ImageWbmp ($im, "test.wbmp", 0); The warning is no longer generated.
