1bb6f9fb10 perf: Add yield and fix double comparison 
- add a yield () function that's called before every test. It reduced the std
dev slightly for me
- fix double comparisons to not just compare the integer part

bcb7863f00 Move target tolerance to cairo_test_target structure (should let single-pixel SVG errors pass) 
Previously we were setting the target tolerance based on the surface
type. But that doesn't work as multiple backends will provide a surface
of type meta. So instead we put the tolerance as a value in the
cairo_test_target data structure.

With this change, some single-pixel errors of 1 in the SVG backend
should now be ignored.

d716020db2 Generate Type 1 fonts from glyph outlines 
This patch generates Type 1 fonts for the PS/PDF backends when TrueType
or Type 1 subsetting fails. This has the advantage over the current
Type 3 fallback of reduced font size and better quality rendering
in some PDF viewers. xpdf shows a large improvement in text display
quality with this patch.

d81de15804 Fix Type 1 embedding in PDF 
PDF Files with Type 1 fonts fail to open in any version of
ghostscript prior to 8.54. The problem is the hex encoding of the
encrypted portion of the font. The PDF reference says this should
only be in binary.

2fa0228d63 Two big improvements to bring the std. deviation down to where we want it. 
1. Remove all the alarm/signal code, which just isn't doing what we want for some reason.
   Instead, for now we'll simply run for a fixed number of iterations, (perhaps we
   can tune that per test later).

2. Before computing mean and stdandard deviation of runs, sort them all and discard the
   top and bottom 20% of the values.

Now the standard deviation for the paint test is generally 2% or less.

d1834cca19 test: Ignore single-bit errors for SVG backend. 
The interface of the various buffer/image_diff functions is improved to
provide the maximum pixel difference in addition to the number of pixels
that differ. This value can then be used to compare against a per-backend
tolerance.

Currently I've set the SVG backend's tolerance to 1 to handle some issues
we're currently seeing of single-bit differences on different systems, (but
we're not exactly sure why yet).

Also I improved the image_diff routines to properly report a status value
on failure rather than the bogus value of -1 for pixels_changed.

d52a1f762d Move test-specific stuff out of boilerplate/ and back into test/ 
This now gives us two separate libtool convenience libraries,
so they have to have separate names now:
libcairoboilerplate.la and libcairotest.la.
