Okay, you can now specify an arbitary object which will be used at a particular
date - couldn't see how to implement a daily calendar though (at least not
without resorting to perl). POV is very fussy about what it'll read.... ;)

Here's the new calendar code...

#version 3.5;


// called by main macro
#macro MakeTOU(CalStr, XTrans, YTrans, CalFont, CalExt, CalSpace)
  text {
    ttf                   // font type (only TrueType format for now)
    CalFont,              // Microsoft Windows-format TrueType font file name
    CalStr,               // the string to create
    CalExt,               // the extrusion depth
    CalSpace              // inter-character spacing
    translate <XTrans,YTrans,0>
  }
#end

/*
Params for MakeCal:
Year = Gregorian Year [int]
Month = Gregorian Month [int 1 -12]
MarkDay = if not 0, unions CalObj with that day
CalXOff = space between dates [num]
CalYoff = space between rows [num]
CalFont = font to use [string]
CalExt = extrusion on text object [num]
CalSpace = inter-char spacing [num]
DayOff = day off-set, [num] 0=sunday, 1=monday, ... 6=saturday
CenterOff = x-adjust for month-year header [num] adjust for centering of heading
CalObj = object to use at Day
*/
#macro MakeCal(Year, Month, MarkDay, CalXOff, CalYOff, CalFont, CalExt,
CalSpace, DayOff, CenterOff, CalObj)
  #local YTrans = 0;
  #local XTrans = 0;
