Some of these functions can be found in POSIX (e.g. look
at the florist package for GNAT). If you are using GNAT,
also look at the GNAT.xxx library routines (e.g. there is
one for reading directories, and GNAT.OS_Lib has a Spawn
routine for calling executables that works on all targets,
as well as other useful stuff).

P.S. The pixel stuff seems entirely at the wrong level to
assume that a universal package is possible, it is more
appropriate to standardize on the use of a higher level
graphics package than try to mess with pixels, which is
simply not possible in some environments.
