Version 2.0...

 - provides support for multiple injections or concaminant antibody
staining.

 - allows one to specify multiple injection and label strengths.
This allows one to draw injection halos, as well as represent
subsequent labeling in a more realistic manner.

 - provides routines for adding, subtracting, and multiplying
analysis results together.  It also allows one to compare data and
analyses by superimposing them together.

 - numbers all records, to help keep track of ones results.

 - allows one to change an injection or label's graphical layer,
pushing it back or popping it to front.

 - allows one to double the resolution of the analysis heatmap.

 - has a modified mk_areas utility that allows one to assure that
area boundaries are coterminous.

Version 1.2...

 - has a control panel that is informative and friendly, and more
messages are shown in the message window throughout the database's
operation.

 - adds write-protection for records, so important data won't be
changed or erased.  It is toggled by clicking on the selected record's
name, and is the default for data saved under previous versions of
Xanat.

 - introduces an additional draw mode, "area," where areas can be
selected or deselected as injections and label with mouse clicks
within their regions.

 - changes the label objects to a less obnoxious color, and treats
the data and analysis color maps independently.

 - fixes sundry bugs, too numerous and minor to mention.

Version 1.1...

 - fixes a major bug in the search algorithm.

 - uses a more sophisticated superposition analysis algorithm that
takes into account fractional overlap, instead of just raw overlap
size.

 - includes conversions to support binary file I/O on both big endian
(Intel) and little endian (MIPS, Sparc) processors, so that one can
now run Xanat on IBM PCs running the Linux operating system.
