fixed select background color when changed via X resources (backported appropriate BWidgets bug-fix)
fixed local views redrawing upon scene saving
added tag type "RP" to block access to certain properties of an object via the property GUI
ExtrNC objects may no longer, erroneously, be associated with materials
improved handling of AutoFocus in various dialogs
added last used tool facility to Tools main menu
added keyboard shortcuts to set point coordinates in the direct point editing dialog (using or )
added "Revert" parameter to ExtrNC object
ExtrNC objects now draw a direction arrow (like NCurve objects)
ExtrNC objects may now extract the complete surface boundary
the standard ConcatNC knot type is now "Custom"
Cap objects can now also create caps from non-planar curves (by splitting the curve into four pieces and building a Gordon surface)
in direct connection with the above, Gordon surfaces now support rational curves for the special case of a Coons patch configuration (four curves)
improved speed of object picking in shaded views
added Split PolyMesh modelling tool
added clamping of NURBS patches (new scripting interface commands "clampNPU" and "clampNPV" and new main menu entries "Tools/NURBPatch/Clamp")
added "rescaleKnNP" command to rescale the knot vectors of NURBS patches and main menu entries "Tools/NURBPatch/Rescale Knots to Range" as well as "Tools/NURBPatch/Rescale Knots to Mindist"
added "insknNPU"/"insknNPV" commands and tools (new main menu entries "Tools/NURBPatch/Insert Knot U" and "Tools/NURBPatch/Insert Knot V") to insert knots into NURBS patch knot vectors
added "splitNPU"/"splitNPV" commands and tools (new main menu entries "Tools/NURBPatch/Split U" and "Tools/NURBPatch/Split V") to split NURBS patches at defined parametric values
added "extrNP" command and tool (new main menu entry "Tools/NURBPatch/Extract Patch") to extract a sub-patch from a NURBS patch
improved knot type handling in remove knot tool
added "trimNC" command and tool (new main menu entry "Tools/NURBPatchTrim")
sweep cross sections may now be scaled independently in x- and y-dimension by using the y- and z-dimensions of the scaling curve
sweep and birail objects now support 0 as number of desired sections and derive the sections from the trajectory or first rail curve respectively
birail objects now support 1 and 2 sections properly
added antialiasing drawing option for lines
added hidden/wizard preference options for line width: "LineWidth" and "SelLineWidth" (set via ayamrc file)
improved drawing of selected curves in Shade&Draw views
improved shading quality of NURBS surfaces in STESS mode
revived STESS drawing of trimmed NURBS surfaces
added DXF import/export plugin dxfio
added X3D import/export plugin x3dio
Mops import is now a plugin
Wavefront OBJ import/export is now a plugin
files may now be imported using the normal "File/Open" and "File/Insert" menu entries (Ayam will load the right plugin automatically and open the corresponding import options dialog, pre-seeded with the right filename)
likewise, scenes may be exported using "File/Save as" and choosing a filename with an extension
improved scalefactor option usage in rrib plugin
added option to write binary 3DMF files
added ReadCurves/WriteCurves/WriteSelected/ScaleFactor/RescaleKnots options to 3DMF import/export
added proper trim curve support to 3DMF export/import
all import options that scale NURBS patch knots now also scale the trim curves properly
added ReadSTrim import option to mfio, onio, objio, and rrib
