---------------------------------

Dithering can now be performed without autoguiding, by sending short pulses to the telescope:

this is useful if your mount is "too" precise on tracking, to avoid using the same pixels in all subs of a sequence.

The 3D graph is drawn with anti-aliasing and can be zoomed:

The resize command has options for duplicating the image and performing gamma correction:

Live annotations, useful for making animations, now support custom date/time formats:

Demosaic RGB, visualization and other commands are faster thanks to new SIMD AVX code which can process 8 pixels at a time.
