Started work on the Tklib 0.6 release.
[Bug 3603562]: Allow the confinement of the crosshairs to one or more
rectangular bounding boxes. Bumped version to 1.1.
Removed superfluous Tcl version check in plotchart package index.
Fixed issues with plotchart tests: Code requires Tcl 8.5 now. Fixed abort message to be properly caught by sak test runner. Added check for Tk, and fixed tk constraint setup. Hackish. Should put Tk presence properly into the constraint, and update all tests.
Corrected the tests - the type of coordinate system must be set explicitly (only within the context of the tests)
Converted test file back from dos to unix line-endings.
Fixed plotcontour-1.0 not properly cleaning up its main canvas. All tests pass.
Merged plotchart test corrections into the release.
Accepted changes by Frank Gover for robustness of bbox handles. Accepted plotchart based examples for multiple bounded crosshairs.
Do not invoke the tracking callback while the crosshairs are out of bounds.
Extend the set of tests for the coordinate transformation procedures.
This revealed that the procedure pixelToCoords had not been updated for
the various transformation options. This has now been corrected.
Other changes: explicitly take care of an expected value of 0 and 
more accurate conversion factor degrees to radians.
Document the subtext subcommands.
Compute the new margins based on the presence or absence of subtexts to the axes.
Bumped version to 2.1.0 to reflect the addition of these subcommands and the
repair of the pixelToCoords procedure.
Correct the use of options for the vertical subtext.
Add missing procedures from previous checkin.
Merged latest crosshair work to the pending release.
Merged latest plotchart work into the pending release.
Merged trunk changes (embedded docs) to pending release.
Fixed old urls in various locations, added meta files to repository to make checkout like distribution.
Updated sak code to the latest from tcllib.
Version fixes
Full regeneration of the embedded docs, proper nav links, extended toc set.
