Log Message:
Mostly cosmetic changes that enable plplot to compiled with (almost) no warnings, even with gcc -Wall.

Most changes are just casts, and most of them are tcl/tk related. For tcl/tk-8.4, no warnings occurs.
Also tested with tcl/tk-8.3, where some warnings remain.
There are no java/f77/cxx/python/octave changes.
