[dev-context] encodings

Hi, I added a new command \showpatterns which produces a table of loaded patterns; btw, czech and polish need testing since we move to latin modern exclusively (pl0 an il2 are only used for plr and csr fonts so we may as well drop loading patterns for these encodings; user can use regimes which will then map onto qx and ec) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
