Make linear and curvilinear texture coordinate generation consistent with each other in
the useLinearTexture branch of buildCurvedTexture.  This fixed an image offset issue
with overlapping regions.

Iteration optimizations and generalization of tile building logic and improvements
building colorbytes from RangeSets
if constant alpha use inverse alpha value in TransparencyAttributes for both 3 and 1 byte
BufferedImage types.  From Ghansham.
remove some commented-out code - getting hard to read.
put the fast_table lookup in the correct place
add some new unit specs from the ECHAM5 model
oops, remove a little bit test code
Include 'colspan' in the list of attributes
take out unncessary ImageComponet updates from the buildTexture methods
add some documentation in the build texture methods.  Make some expressions
in these methods a little more readable.
check missingTransparent (default=true) to determine color space dimension.  Transparent
missing values needs RGBA or Gray+Alpha (if we get it working).  Patch to
make this work for RGBComposite.  GraphicsModeControl and Display.MissingTransparent
are checked (the latter has precedence).
applyTexture: if constant_alpha=NaN (pick up transparency from table) then
setTransparency(0), the default in the attribute.
Add instructions for release
