+ Limitations of this code:
+ 1. Transparency is lost on export. (Apparently a limitation of the EMF format.)
+ 2. Probably messes up if row stride != w*4
+ 3. There is still a small memory leak somewhere, possibly in a pixbuf created in a routine
+ that calls this one and passes px, but never removes the rest of the pixbuf. The first time
+ this is called it leaked 5M (in one test) and each subsequent call leaked around 200K more.
+ If this routine is reduced to
+ if(1)return(0);
+ and called for a single 1280 x 1024 image then the program leaks 11M per call, or roughly the
+ size of two bitmaps.

+ A point (x,y) on the arc can be found by:
+
+ {x,y} = {cx,cy} + {cosF,-sinF,sinF,cosF} x {rxcosT,rysinT}
+
+ where
+ {cx,cy} is the center of the ellipse
+ F is the rotation angle of the X axis of the ellipse from the true X axis
+ T is the rotation angle around the ellipse
+ {,,,} is the rotation matrix
+ rx,ry are the radii of the ellipse's axes
+
+ For SVG parameterization need two points.
+ Arbitrarily we can use T=0 and T=pi
+ Since the sweep is 180 the flags are always 0:
+
+ F is in RADIANS, but the SVGEllipticalArc needs degrees!

+Method:
+ 1. For all ordered text objects which are sequential and share the same esc.
+ 2. For the first only pull x,y,esc and save, these define origin and rotation.
+ 3. Save the text object.
+ 4. Phase I: For all saved text objects construct lines.
+ 5. Check for allowed overlaps on sequential saved text object bounding rectangles.
+ 6 If found merge second with first, check next one.
+ 7. If not found, start a new complex (line).
+ 8. Phase II; for all lines construct paragraphs.
+ 9. Check alignment and line spacing of preceding line with current line.
+ 10. if alignment is the same, and line spacing is compatible merge current line into
+ current paragraph. Reaverage line spacing over all lines in paragraph. Check next one.
+ 11. If alignment does not match start a new paragraph.
+ (Test program)
+ 12. Over all phase II paragraphs
+ 13. Over all phase I lines in each paragraph.
+ 14. Over all text objects in each line.
+ Emit SVG corresponding to this construct to a file dump.svg.
+ (Conversion to other file types would be modeled on this example.)
+ 15. Clean up.
+ (General program)
+ Like for the Test program, but final representation may not be SVG.
+ Text object and bounding rectangle memory would all be released. If another set of
+ text will be processed then hang onto both Freetype and Fontconfig structures. If no
+ other text will be processed here, then also release Freetype structures. If the caller uses
+ Fontconfig elsewhere then do not release it, otherwise, do so.
+
+NOTE ON COORDINATES: x is positive to the right, y is positive down. So (0,0) is the upper left corner, and the
+lower left corner of a rectangle has a LARGER Y coordinate than the upper left. Ie, LL=(10,10) UR=(30,5) is typical.

+ \brief Attempt to figure out the original organization, in lines and paragraphs, of the text objects.
+ The method is:
+ 1. Generate complexes from the text objects (strings) by overlaps (optionally allowing up to two spaces to be
+ added) to produce larger rectangles. Complexes that are more or less sequential and have 2 or more text objects
+ are TR_LINEs, therwise they are TR_TEXT.
+ 2. Group sequential complexes (TR_LINE or TR_TEXT) into TR_PARA_UJ (paragraphs,by smooth progression in vertical
+ position down page).
+ 3. Analyze the paragraphs to classify them as Left/Center/Right justified (possibly with indentation.) If
+ they do not fall into any of these categories break that one back down into TR_LINE/TR_TEXT.
+ 4. Return the number of complex text objects.
+ \returns Number of complexes. (>=1, <= number of text objects.) <0 is an error.
+ \param tri pointer to the TR_INFO structure holding the data, which will also hold the results.

+
+ Limitations of this code:
+ 1. Images lose their rotation, one corner stays in the same place.
+ 2. Transparency is lost on export. (A limitation of the WMF format.)
+ 3. Probably messes up if row stride != w*4
+ 4. There is still a small memory leak somewhere, possibly in a pixbuf created in a routine
+ that calls this one and passes px, but never removes the rest of the pixbuf. The first time
+ this is called it leaked 5M (in one test) and each subsequent call leaked around 200K more.
+ If this routine is reduced to
+ if(1)return(0);
+ and called for a single 1280 x 1024 image then the program leaks 11M per call, or roughly the
+ size of two bitmaps.
