+Unimplemented functionality
+	- tesselation and callbacks
+	- trimming
+	- setting NURBS properties (-> sampling etc.)
+Differences from C++ source
+	- no pooling
+	- pointers to arrays are replaced by CArrayOf... classes and their methods
+Unimplemented or incomplete "calltree top" methods (according to glu.def in Mesa 6.5)
+	gluBeginTrim
+	gluDeleteNurbsRenderer - won't be needed
+	gluEndTrim
+	gluGetNurbsProperty
+	gluLoadSamplingMatrices
+	gluNurbsCallback
+	gluNurbsCallbackData
+	gluNurbsCallbackDataEXT
+	gluNurbsCurve - TODO type switch
+	gluNurbsProperty
+	gluPwlCurve
+	gluQuadricCallback - not a NURBS method
+As of files
+	- Arc[ST]dirSorter.java - unimplemented (part of tesselation)
+	- Backend.java:194 - wireframe quads - part of tesselation/callback
+	- Curve.java:141-204 - culling
+	- DisplayList.java:57 - append to DL - not sure whether it will be needed
+	- GLUnurbs.java	:443,484 - error values
+			:445 - trimming
+			:512 - error handling (callback)
+			:530 - loadGLmatrices
+			:786 - nuid - nurbs object id - won't be needed I think
+			:803 - end trim
+	- GLUwNURBS.java:68,176 - NUBRS properties
+	- Knotspec.java	:371 - copying in general case (more than 4 coords)
+			:517 - copying with more than 4 coords
+			:556 - pt_oo_sum default
+	- Knotvector.java:165 - show method (probably debugging)
+	- Mapdesc.java	:354 - get property
+			:435 - xFormMat - change param cp to CArrayOfFloats; probably sampling functionality
+	- Maplist.java:68 - clear ?
+	- OpenGLCurveEvaluator.java	:132 - tess./callback code
+					:168 - mapgrid1f
+					:190 - tess./callback code (output triangles)
+	- OpenGLSurfaceEvaluator.java	:77 . tess./callback code
+					:81 - glGetIntegerValue
+					:114 - tess./callback code
+					:117 - Level of detail
+					:144,161,201 - tess./callback code - output triangles
+	- Patch.java:55 - constructor stuff ?
+	- Patchlist.java:55 - constructor stuff ?
+			:97 - cull check
+			:105 - step size
+			:115 - need of sampling subdivision
+			:126 - need of subdivision
+			:137 - need of non sampling subd.
+			:146 - bbox (??)
+	-Quilt.java	:254 - culling
+			:282 - rates
+	-Subdivider.java - all TODOs - it's stuff about trimming probably
+			 :545 - jumpbuffer - not sure purpose it exactly served in original source
