Nico Weber 06b9633da5 LibPDF: For indexed images with 1, 2 or 4 bpp, do not repeat bit pattern 
When upsampling e.g. the 4-bit value 0b1101 to 8-bit, we used to repeat
the value to fill the full 8-bits, e.g. 0b11011101. This maps RGB colors
to 8-bit nicely, but is the wrong thing to do for palette indices.
Stop doing this for palette indices.

Fixes "Indexed color space index out of range" for 11 files in the
PDF/A 0000.zip test set now that we correctly handle palette indices
as of the previous commit:
