Added a new chapter at the end of Part III, Developer's Guide to PHPlot

      </p></dd><dt><span class="term">2010-11-18</span></dt><dd><p>
Restructuring.
Too much advanced material was ending up in the basic programming chapter
"Concepts". There is now a new chapter "Advanced", which includes the material
on Callbacks (demoted from chapter to section), plus two sections previously
in "Concepts": custom data color callback, and truecolor images.
Also moved the Functions by Category chapter after Examples, not before.
      </p><p>
Added new section "Tuning Parameters" in the Advanced chapter, to provide
more information about class variables that can be set to adjust plot
appearance.

Changes for new X and Y axis position defaults.
      </p></dd><dt><span class="term">2010-09-13</span></dt><dd><p>
Documentation was added and changes made for horizontal plot types and their
new data types.
(This was previously an experimental feature, documented in a text file
included in with the PHPlot release.)
Three new examples were added, showing horizontal plot types.
      </p><p>
A terminology change was necessary due to the introduction of horizontal plots
and dual use of Y data labels, which are now symmetrical with X data labels.
Previously, <span class="emphasis"><em>data labels</em></span> referred to labels from the
data array which were displayed along the X axis or top edge, and
<span class="emphasis"><em>Y data labels</em></span> referred to the Y bar value labels
displayed within the plot area.
The manual now distinguishes these by type, not axis. <span class="emphasis"><em>Axis data
labels</em></span> are labels from the data array which are displayed along the
independent variable axis, and <span class="emphasis"><em>data value labels</em></span> show the
value of a data point using the dependent variable. The general term
<span class="emphasis"><em>data labels</em></span> is used to refer to both types of labels. (For
example, SetXDataLabelAngle applies to data labels - both axis data labels
and data value labels.)
      </p></dd><dt><span class="term">2010-09-08</span></dt><dd><p>
Changes were made throughout the manual to support production of a PDF
version. The changes should have only a small impact on the HTML version.

after PHPlot-5.1.2 this works differently and hopefully better.

Removed the Extra Data Processing section in the Concepts chapter, and
removed the <code class="filename">phplot_data.php</code> file from the installation

Added new chapter to Developer's Guide on the callbacks feature, and added
documentation of the 3 public functions used with callbacks to the Function
Reference. The text is based on the <code class="filename">Callbacks</code> file
which was included with PHPlot-5.0.4 (and will removed in the next release).
Although this is now documented in the manual,
the callbacks feature is still considered experimental.

      </p><p>
Document the requirement that style arrays use zero-based sequential integer
indexes only. This includes colors, point shapes/sizes, line widths, and
line styles.
