Small text on a hir-res screen

[Chris Olson]

Here's the fucntions I use for drawing tiny text on a hi-res screen. 
Seems to work fine for me.  I leave it as an exercise for the reader to 
add proper error checking and screen resolution detection (stripped for 
brevity)
Note:
   linewin is an offscreen window which is font height tall and 320 
pixels wide (in hires).

void
Main::DrawText (Coord x,
               Coord y,
               Char* str)
{
   BitmapPtr bmp;
   RectangleType r;
 
   bmp = draw.GetWindowBitmap(lineWin);
  
   WinSetDrawWindow(lineWin);
   r.topLeft.x = 0;
   r.topLeft.y = 0;
   r.extent.x = 320;
   r.extent.y = FntCharHeight();
   WinEraseRectangle(&r, 0);
  
   WinDrawChars(buffer, StrLen(buffer), 0, 0);
  
   BmpSetDensity(bmp, kDensityDouble);
  
   WinCopyRectangle(lineWin, WinGetDisplayWindow(), &r, x, y, 
winPaint);   
  
   BmpSetDensity(bmp, kDensityLow);

   WinSetDrawWindow(WinGetDisplayWindow());
} // DrawText
