Nico Weber 007d7cdd53 LibPDF: Fix sign (and fixed point) in glyph decoding opcode 24 
Two bugs:

1. We decoded a u32, not an i32 as the spec wants
2. (minor) Our fixed-point divisor was off by one

Fixes text rendering in Bakke2010a.pdf in pdffiles, and rendering of
other fonts with negative width adjustments from optcode 255.
That PDF was produced by "Apple pstopdf" and uses font SFBX1200,
which is apparently a variant of Computer Modern. So maybe this
helps with lots of PDFs produced from TeX files, but I haven't
checked that.
