[split] Jorge's Retracer Thread: darker ink, retracing of text and drawings

[Jorge_Stolfi]

More hallucinations in psychedelic color on page f8r.  Mostly the usual stuff.
   
This clip spans the middle part (around the plant's stem) of lines 9-12 of page f8r. As usual it shows what seem to be at least three layers of ink: original (Rt0), a gneral restoration (Rt1), and at least one set of scattered retracings (Rt2).
   
    This is a false-color image created by combining three narrow-band images from the Lazarus 2010 set -- MB940IR_012, MB700IR_008, and MB535GN_004 -- as the red, green, and blue channels of an RGB image.  No processing was performed other than affinely scaling the samples in each channel to the full 0-1 range, with ImageMagick's "-normalize" directive.  The fuzzy blue areas are bleedthrough of the green paint from f8v.

    (A) Original (Rt0) parts of the p. (B) Original traces of the plant outline.  (C ) The tip of the plume is Rt0; the rest is Rt1, retraced closckwise.
   
    (J) Restored (Rt1) parts of the p. (K) Rt1 traces of the plant outline. (LQ) The left leg of the t and the tail of the l are Rt0 or Rt1; the rest of the word is mostly Rt2.
   
    (P) These glyphs are presumably Rt2.
