--User changes

-Add buttons to copy and paste affine transforms.
 -Show xform names on the column headers of the xaos table.
 -Add a color-coded third column to the variations tree which shows any properties of each variation which are non-standard.
 -Draw a transparent circle over hovered xforms.
 -Change how xforms respond to dragging. Rotate only is now the default, and scale will only happen with shift.
 --Optionally do scale and rotate when holding shift, via a setting in the options dialog.

--Bug fixes
 -Snapping when dragging was wrong sometimes.
 -The program would very rarely crash on startup due to some values being in an uninitialized state.

--Code changes
 -Change almost every variation to use fma() in OpenCL when doing computations of the form a * b + c. This provides a slight speedup, mostly in double precision mode.
 -Also apply fma() to affine calcs.
 -Cleanup of OpenGL affine drawing code.
 -Separate the concept of hovering and selecting xforms.
