--User changes

-Better handling of crossed min/max DE filter values on the GUI.
 -Changes to spatial and density filter values will no longer restart the entire render.
 -Support reading cam_zoom from xml as zoom since JWildfire uses cam_zoom.
 -Change drag n drop behavior: the default is now to append, hold Ctrl to overwrite.
 -Set max value of zoom to 25 because it will crash with values around 28 or 29 due to numeric overflow when scaling quality.
 -Update links in About Dialog.
 -Rename some controls in Options Dialog.
 -Move the color curves control to the Palette tab.

--Bug fixes
 -Remove extra space in info tree text when dealing with a linked xform.
 -Update summary xform name field whenever xform name changes.
 -Get rid of selection border on summary tab xform tree cells.
 -Only add variations from Xml that have a non-zero weight. There seemed to be spurious flattens coming from Apo with a weight of 0.

--Code changes
 -Gutters are now a fixed size of 8 * supersample.
 -Use stl data() member to get pointer to first element instead of &vec[0].
 -Eliminate extra calls in renderer to ComputeBounds(), CreateSpatialFilter() and CreateTemporalFilter() to only be done at the start of a render.
 -Another attempt at vectorizing LogScaleDensityFilter(). Vectorizes, but not sure if it helps.
 -Some other loop optimizations in Renderer.
 -No longer check temporal samples in response to some control changes, they are always 1 in the interactive renderer.
