+This class encapsulates the functionality of printing out an application
+document. A new class must be derived and members overridden to respond to calls
+such as OnPrintPage and HasPage and to render the print image onto an associated
+\helpref{wxDC}{wxdc}. Instances of this class are passed to wxPrinter::Print or
+to a wxPrintPreview object to initiate printing or previewing.
+
+Your derived wxPrintout is responsible for drawing both the preview image and
+the printed page. If your windows' drawing routines accept an arbitrary DC as an
+argument, you can re-use those routines within your wxPrintout subclass to draw
+the printout image. You may also add additional drawing elements within your
+wxPrintout subclass, like headers, footers, and/or page numbers. However, the
+image on the printed page will often differ from the image drawn on the screen,
+as will the print preview image -- not just in the presence of headers and
+footers, but typically in scale. A high-resolution printer presents a much
+larger drawing surface (i.e., a higher-resolution DC); a zoomed-out preview
+image presents a much smaller drawing surface (lower-resolution DC). By using
+the routines FitThisSizeToXXX() and/or MapScreenSizeToXXX() within your
+wxPrintout subclass to set the user scale and origin of the associated DC, you
+can easily use a single drawing routine to draw on your application's windows,
+to create the print preview image, and to create the printed paper image, and
+achieve a common appearance to the preview image and the printed page.

+
+\func{wxRect}{GetPaperRectPixels}{}
+
+Returns the rectangle that corresponds to the entire paper in pixels, called the
+\em{paper rectangle}. This distinction between paper rectangle and page
+rectangle reflects the fact that most printers cannot print all the way to the
+edge of the paper. The page rectangle is a rectangle whose top left corner is at
+(0,0) and whose width and height are given by
+\helpref{wxDC::GetPageSizePixels}{wxprintoutgetpagesizepixels}. On MSW and Mac,
+the page rectangle gives the printable area of the paper, while the paper
+rectangle represents the entire paper, including non-printable borders. Thus,
+the rectangle returned by GetPaperRectPixels will have a top left corner whose
+coordinates are small negative numbers and the bottom right corner will have
+values somewhat larger than the width and height given by
+\helpref{wxDC::GetPageSizePixels}{wxprintoutgetpagesizepixels}. On other
+platforms and for PostScript printing, the paper is treated as if its entire
+area were printable, so this function will return the same rectangle as the page
+rectangle.

+\membersection{wxPrintout::FitThisSizeToPaper}\label{wxprintoutfitthissizetopaper}
+
+\func{void}{FitThisSizeToPaper}{\param{const wxSize\& }{imageSize}}
+
+Set the user scale and device origin of the wxDC associated with this wxPrintout
+so that the given image size fits entirely within the paper and the origin is at
+the top left corner of the paper. Note that with most printers, the region
+around the edges of the paper are not printable so that the edges of the image
+could be cut off. Use this if you're managing your own page margins.
+
+\membersection{wxPrintout::FitThisSizeToPage}\label{wxprintoutfitthissizetopage}

+
+Set the user scale and device origin of the wxDC associated with this wxPrintout
+so that the given image size fits entirely within the page rectangle and the
+origin is at the top left corner of the page rectangle. On MSW and Mac, the page
+rectangle is the printable area of the page. On other platforms and PostScript
+printing, the page rectangle is the entire paper. Use this if you want your
+printed image as large as possible, but with the caveat that on some platforms,
+portions of the image might be cut off at the edges.

+
+\func{void}{FitThisSizeToPageMargins}{\param{const wxSize\& }{imageSize}, \param{const wxPageSetupDialogData\& }{pageSetupData}}
+
+Set the user scale and device origin of the wxDC associated with this wxPrintout
+so that the given image size fits entirely within the page margins set in the
+given wxPageSetupDialogData object. This function provides the greatest
+consistency across all platforms because it does not depend on having access to
+the printable area of the paper. Note that on Mac, the native wxPageSetupDialog
+does not let you set the page margins; you'll have to provide your own mechanism,
+or you can use the Mac-only class wxMacPageMarginsDialog.

+
+\membersection{wxPrintout::MapScreenSizeToPaper}\label{wxprintoutmapscreensizetopaper}
+
+\func{void}{MapScreenSizeToPaper}{}
+
+Set the user scale and device origin of the wxDC associated with this wxPrintout
+so that the printed page matches the screen size as closely as possible
+and the logical origin is in the top left corner of the paper rectangle.
+That is,
+a 100-pixel object on screen should appear at the same size on the printed page. (It
+will, of course, be larger or smaller in the preview image, depending on the zoom
+factor.) Use this if you want WYSIWYG behavior, e.g., in a text editor.

+
+\membersection{wxPrintout::MapScreenSizeToPage}\label{wxprintoutmapscreensizetopage}

+\membersection{wxPrintout::MapScreenSizeToDevice}\label{wxprintoutmapscreensizetodevice}
+
+\func{void}{MapScreenSizeToDevice}{}
+
+Set the user scale and device origin of the wxDC associated with this wxPrintout
+so that one screen pixel maps to one device pixel on the DC. That is, the user
+scale is set to (1,1) and the device origin is set to (0,0). Use this if you
+want to do your own scaling prior to calling wxDC drawing calls, for example, if
+your underlying model is floating-point and you want to achieve maximum drawing
+precision on high-resolution printers. (Note that while the underlying drawing
+model of Mac OS X is floating-point, wxWidgets's drawing model scales from integer
+coordinates.) You can use the GetLogicalXXXRect() routines below to obtain the
+paper rectangle, page rectangle, or page margins rectangle to perform your own scaling.
