Things from the last week

 * 1) Fixed engine_free callback, now no memory leaks on LANPR side.
 * 2) Fixed LANPR shader free problems.
 * 3) Software mode now support camera lens shift. Should be usable with any camera configurations now. (Only fisheye not implemented)
 * 4) Implemented Image-space chain connection to reduce jaggy lines.
 * 5) After some back and forth, finally settled down on a more solid design for Bridging LANPR with Blender and how to use GPencil modifiers. More information to come.
 * 6) Minor bug fixes.

Still to come

 * 1) Intersection lines needs near-far clipping before perspective division and coordinate shift. Need to prove this isn't needed.
 * 2) Perspective correction for occlusion points on the chains or use world-space split points.
 * 3) Still have some VBO utility structures not cleared correctly when LANPR exits.
 * 4) Move stroke generation modifier into Object modifiers as part of the design.
 * 5) Implement the new LANPR to GP path, including selections and generation.
 * 6) Image-space chaining reported to have some bugs in it. Look into it during the weekend.

I typically do more things in the weekends because I'm still enrolling in school. So expect updates before Monday. Happy weekend every one! :)
