Creation of fonts-not-found with Metafont

In case the printer driver cannot find a font that is needed and in case the environment variable ``CALLMF'' is set, the contents of this variable is used for calling an ARexx script file.

This is called with the three following parameters, in order to create the font that was not found:

<#114#>-- <#114#> with the name of the font to be created, with the resolution of the font in DPI and with the resolution, with which DVIprint<#115#><#115#> is printing.

This means, that after

;SPMnbsp;;SPMnbsp;;SPMnbsp;;SPMnbsp;;SPMnbsp;;SPMnbsp;;SPMnbsp;;SPMnbsp;<#116#>setenv CALLMF callmf<#116#>

DVIprint<#117#><#117#> would call the script with

;SPMnbsp;;SPMnbsp;;SPMnbsp;;SPMnbsp;;SPMnbsp;;SPMnbsp;;SPMnbsp;;SPMnbsp;<#118#>callmf cmr10 360 300<#118#>

in case the font ``cmr10'' with the resolution ``magstep1'' should not be found and the printer in HP-DeskJet mode would at the time print with a resolution of 300 dpi.
