BRL-CAD 7.6.4 Released

This release adds several bug fixes and feature enhancements including a new geometry creation interface to mged. This new interface supports reverse modeling geometry from existing objects through point collection techniques. New geometry creation commands read point data sets in a simple text file format, recognizing categories and collections of points representing prescribed geometric shapes. Using point-acquisition devices such as X-Station Vulcan advanced surveying systems from Arc Second Inc., points may be collected and provided to mged factilitating the generation of geometry models. Collection techniques are recognized and already implemented for polygonal plates, cylinders, spheres, point clouds, and more. More details will be provided in a later release as these new features continue to be tested, improved, and documented.

The list of changes from 7.6.0 to 7.6.4 include:

* auto-locate mged external apps regardless of PATH
* mged utilizes a local display if unspecified/unset
* set default mged Escape key binding to reject
* fixed 'benchmark' tool resource searching
* added -u option to mged "make_bb" to allow air
* fixed IBM AIX compiler support issues
* head/tail -n usage posix compliance
* fixed jove compilation issues
* fixed conversion bug in the dxf-g converter
* point parsing/import interface to mged
* fixed bug in export of NMG primitives
* fixed itcl configuration issue

* improved mged 'tol' command tolerance value checks
* fixed tgc absolute tesselation tolerance issue
* optional build support checks for X11 and OpenGL
* improved Windows build support
* isst observer 2x screen magnification
* added los and material name support to librtserver
* improved 64bit support for ADRT
* updated manual page documentation
