Having phase=verify for gpg signing caused bad signature errors when the files were uploaded to sonatype. Changing to phase=deploy seems to fix this. Not sure exactly why.
Newt native windows appear at size 128by128 before they are resized to the size of their container (a JFrame for example). This can cause Axes with constraints (especially aspect ratio constraints) to appear differently than expected. To combat this, GlimpseCanvas should not be added to the frame until it is fully visible. Modified Example.java to reflect this.
Turned off javadoc generation in pom.xml (by default) -- javadoc still generated for Maven Central build.
Updated docking example to include example of using GlimpseCanvas inside of docking framework.
Fixed TrackPainter.deleteAll() -- more closely matches TrackPainter.deleteTrack().
IntervalQuadTree would not be able to find elements if their times changed (even if their unique identifier was the same).
Fixed issues with previous IntervalQuadTree fix.
Fixed LayoutManager and LegendPainter synchronization issues. Refactored how GlimpseCanvas disposal works. GLEventListener dispose() callbacks should no longer cause attached GlimpseLayouts or GlimpsePainters to be disposed. Also removed a number of old and unused classes.
Reversed default CTRL + mouse wheel effect on selected time window.  New behavior: CTRL + wheel up englarges the window, and CTRL + wheel down shrinks the window.
Added experimental polar axis painter.
Fixed synchronization issue with ColorTexture1D.
Re-added dispose() to GlimpseCanvas interface. This prevents breaking existing code by having dispose() basically do what it used to do -- now it's a shortcut for destroy() followed by disposeAttached().
Switched ordering of dispose method calls in Example.java.
