- * ctsim: Added tips to be displayed at startup and via the help menu.
+ New Features:
- * ctsim: Added center-detector concept. Allow for detector array
+ -- ctsim: Added direct Fourier reconstructions (Thanks to

to be any arbitrary distance from center of scanner. As a result,
projection files are not incompatible with previous version of
CTSim.

+ scanning, and rasterization.
+ -- ctsim: Added generic threaded tasks and background manager for
background processing as well as taking advantage of multiple-CPU's
on SMP systems.

+ -- imagefile.cpp: Fixed scaling factor in fftRows
+ -- imagefile.cpp: Fixed bug when performing magnitude() on real-valued
+ image.
+ -- sgp.cpp: Fixed bug in drawCircle.
+ -- distribution: fixed problem with documentation files not
being included with the distribution [Reported by Ian Kay].
+ -- sgp.cpp/ezplot.cpp: Improved plotting with markers.
+ -- fixed ctsimtext shell when giving no parameters to function-name
