* \GPT@catcodes extended for xmlTeX (pdftex.def loads supp-pdf.mkii at begin document where xmlTeX's catcodes are already active).
Changes: * Catcodes are preserved and initialized for loading of pdftex.def and ConTeXt's support files. * ConTeXt's support files have now the extension `.mkii' instead of `.tex'.
The file pdftex.def provides device-specific definitions for color and graphics support when running pdf(La)TeX.
