50 to 60% performance improvement, especially noticeable on high-res
terrain type data:
manage two Lists of ContourStrip, one for closed and one for open.
Greatly reduces
time to search the open list - less comparisons, less arithmetic. (For
contour lines)

------------------------------------------------------------------------

Changed paths:
   M /trunk/core/src/visad/Contour2D.java

modest performance improvement in the high density terrain type grids.

------------------------------------------------------------------------
r5987 | tomw | 2012-11-08 12:29:39 -0600 (Thu, 08 Nov 2012) | 1 line
Changed paths:
   M /trunk/core/src/visad/python/JPythonMethods.java

Added maskOutsideRange() and allow for >=, =>, <=, =< for mask() and find() []
------------------------------------------------------------------------
r5986 | rink | 2012-11-07 10:19:36 -0600 (Wed, 07 Nov 2012) | 2 lines
Changed paths:
   M /trunk/core/src/visad/Contour2D.java

new code to avoid unnecessary array copies with new multiple label logic

------------------------------------------------------------------------
r5985 | rink | 2012-11-05 16:02:23 -0600 (Mon, 05 Nov 2012) | 2 lines
Changed paths:
   M /trunk/core/src/visad/Contour2D.java

new methods in ContourStrip to request start/stop pairs (for new
contour label frequencey logic)

------------------------------------------------------------------------
r5984 | rink | 2012-11-02 12:56:19 -0500 (Fri, 02 Nov 2012) | 2 lines
Changed paths:

Changed paths:
   M /trunk/core/src/visad/bom/ShadowImageByRefFunctionTypeJ3D.java

ImageComponent capabilities should be consistent between
textureToGroup and applyTexture (both need read/write)

------------------------------------------------------------------------
