/** \mainpage libUEMF overview
\section ov Overview
Microsoft's WMF, EMF, and EMF+ metafile types are supported.  In each case functions are provided for reading, constructing, writing, and printing 
metafile records.  The methods used to do that differ somewhat between metafiles, and the simplest
way to get started is to have a look at the example programs provided.  The WMF, EMF, and EMF+ structs and functions are 
marked with U_WMF, U_EMF, U_PMF and U_WMR, U_EMR, and U_PMR prefixes.  (PMF because "+" is a reserved character
in many contexts, so U_EMF+NAME would be a problem.)  Please be aware that normally both EMF and EMF+ files have the ".emf"
file extension, and that it is very common for such files to contain both an EMF and an EMF+ representation of the 
drawing.

\section doxy_limits Documentation issues
There are currently some unresolved issues with Doxygen that result in some structs
not being "defined".  This comes up when several different types of structs have the same
layout.  When this occurs the first one listed on the "typedef struct" is defined but all the
others will only be shown under "typedef struct" referring to the first one.  This is why
clicking on U_RECTL in a function parameter jumps to a typedef struct page,  why U_RECTL is shown
as plain text here, but U_RECT is shown as a link here, and clicking on it jumps directly
to its structure definition.

An additional issue is that the Enumeration names used in WMF are different from those
used in EMF, even when the values are either identical or differ only slightly, and no method 
has been found yet to link one to the other in Doxygen.  At present the only way to look up 
these WMF enumerations is by referencing the following table:

/** \defgroup U_EMF_EMRSETROP2_iMode_Qualifiers EMF Binary Raster Operation Enumeration

  For U_EMRSETROP2 iMode field
  Microsoft name: Binary Raster Operation Enumeration
  WMF manual 2.1.1.2
  
  These codes specify:
    1.  an order of operands (composed of various orders and combinations of: Dest, Pen)
        (There are 2, hence "Binary Raster Operation")
    2.  an order of operators to apply to the operands (composed of Not, Xor, Or, And)
  Only a few of the more common operations are provided here.

  The default is U_R2_COPYPEN.  If this value is changed to something else all subsequenty
  draw operations will use the altered logic.  For instance, if it is set to U_R2_BLACK and
  a red rectangle is drawn it will appear as a black rectangle.

  These codes specify:
    1.  an order of operands (composed of various orders and combinations of: Dest, Src, Pen)
        (There are 3, hence "Ternary Raster Operation")
    2.  an order of operators to apply to the operands (composed of Not, Xor, Or, And)
  Only a few of the more common operations are provided here.
  When the Operation does not use a Src operand the corresponding source bitmap may be
     omitted from the record.

  WMF Manual 2.1.2.3
  WMF Manual 2.1.2.4
  
  Recall that EMF coordinates have UL  closest to {0,0}, LR is below and to the right of UL and so has LARGER
  {x,y} coordinates.  In the following "TOP" is on the horizontal line defined by LR, as it has larger y coordinates,
  which when viewing the EMF file, would actually be on the BOTTOM of the bounding rectangle.  Similarly, left and right
  are reversed.
  
  Microsoft documentation (WMF  manual, section 2.1.2.3) says that the text starts on certain edges of the bounding rectangle.
  That is apparently not true, whether the bounding rectangle is {0,0,-1,-1}, which is effectively no bounding rectangle,
  or if a valid bounding rectangle is specified.  In all cases the text (in Windows XP Preview) starts, has center at, or ends 
  at the center point.  Vertical offsets seem to be defined analogously, but with respect to the height of the font.  The bounding
  rectangle defined for the U_EMRTEXT record appears to be ignored.

  Microsoft documentation (EMF  manual,section 2.2.5) says that the same rectangle is used for "clipping or opaquing" by ExtTextOutA/W.
  That does not seem to occur either.

  Note also that three fields in this file (nBytes, nRecords, nHandles) must be (re)set after the entire EMF
  is constructed, since typically they are not known until then.  bOpenGL may or may not be knowable when this
  header is written.
  
  Note also that rclBounds and rclFrame are supposed to be the region bounding the drawn content within the 
  EMF.  This is generally smaller than the size from szlDevice.  However, since libUEMF does not actually draw
  anything it has no way of knowing what these values are.  Instead when it creates a header it sets these to 
  match the szl* fields.
