Bibble has had lens correction for a while. First PTLens, then it's
own implementation.

Is Bibble's own implementation derived from PTLens as a result of
licensing the algorithmic or coding rights from PTlens or
commissioning the author to do it for them, or is it a new
implementation of their own from scratch?

Originally I beleieve it was an implementation of PTLens and used the
PTlens. However somewhere in V4 it was a new implemtation from
scratch.

And here's the info I was remembering from the help file of 4.8+

About the Lens Database

Up through Bibble 4.7, lens distortion correction in Bibble - provided
in the BPTLens plug-in - was compatible with Tom Neimans' PTLens text
database. Tom has recently changed to using a private binary format
for his database and changed his licensing terms and thus our database
is currently not compatible with his latest database.

Beginning with Bibble 4.8, lens distortion correction has been
reworked and moved inside the main Bibble application. Besides
providing a more integrated solution, we've also added additional
controls to correct Chromatic Aberration and light falloff due to lens
vignetting. All of the lens profiles available with the last (4.7)
version of the BPTLens plugin are also included and supported in
Bibble 4.8. Bibble Labs will provide our own new calibrations as
lenses and cameras are introduced. If you have a lens or camera that
isn't currently supported and would like to ask us to include it,
please visit our Lens Calibration page for information on how to send
us the necessary test shots. In addition to the new controls you will
also find that the lens corrections are applied faster and don't
require as much memory as before.
