gallery updates:
- Null SOP "render info" (automatic setting of obj-level render flags)
  - currently velocity blur only (geo_velocityblur)
- obj/COP2:: "bokeh image generator" (with a very lame UI, though)
- Plot Scanline COP2: draws the RGB values of a single scanline
NEW: Plot Scanline qL COP2
Merged work:
- Plot Scanline qL COP2
- more delta mush work
- retired Xform-by-Points qL SOP (Houdini has Transform Pieces SOP now)
