* added first FPC support, only VGA works to some extend for now
* use -dasmgraph to use assembler routines, otherwise Pascal
equivalents are used
* use -dsupportVESA to support VESA (crashes under FPC for now)
* only dispose vesainfo at closegrph if a vesa card was detected
* changed int32 to longint (int32 is not declared under FPC)
* changed the declaration of almost every procedure in graph.inc to
"far;" becquse otherwise you can't assign them to procvars under TP
real mode (but unexplainable "data segnment too large" errors prevent
it from working under real mode anyway)
