5534c30524 build: Use common rules for making pdiff 
Instead of providing special rules for compiling C files in pdiff, use
the common ones and build a different pdiff for debug and release.

b8a7f8621a Update FSF address 
I updated the Free Software Foundation address using the following script.

for i in $(git grep Temple | cut -d: -f1 )
do
  sed -e 's/59 Temple Place[, -]* Suite 330, Boston, MA *02111-1307[, ]* USA/51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA/' -i "$i"

5926257770 Revamp the build system. 
Quick summary of changes:

  - Move list of cairo source files out of src/Makefile.am and into
    src/Sources.mk,

  - Generate files src/Config.mk and src/Config.mk.win32 that choose
    the right set of source files and headers based on configured
    backends and features.  This drastically simplifies building
    using other build systems.  The src/Makefile.win32 file needs
    to be updated to reflect these changes.

  - Add README files to various directories,

  - Add toplevel HACKING file.

fa9201b9c9 [pdiff] Check for too small images. 
The Laplacian pyramid can only work on images larger than 3x3 due to the
size of its convolution kernel. So if the image is too small return an
error (-1) before attempting to construction the pyramid.

14cab8b020 Correct an off-by-one in the reflection of the convolution index. 
Currently the convolution code uses the formula 2*(N-1)-n to reflect the index
n when n is greater than or equal to N.
This is wrong as n=N -> 2*(N-1)-N = N-2 instead of N-1.

Furthermore when the image is small, e.g. at the highest levels of the
pyramid, this causes the code to index before the start of the array and
causes valgrind to issue a warning.

2ca6a767ee [pdiff] Don't use float math functions if not using gcc with C99 
The float version of many math functions were introduced in C99, and were
causing compile failure on systems like OS X.  We now define them to their
double variant if __USE_ISOC99 is not defined.  We may want to expand it later
to cover non-gcc compilers too, but since this is pdiff only, it's not really
important.

d421a856d0 pdiff: Re-indent all code 
I've given up on trying to preserve the old code formatting
for compatibility. We're not planning on augmenting the algorithm
itself, just integrating it into cairo. So I don't expect to
make changes that we'll be all that interested in pushing
upstream.

41e01d95ed pdiff: Factor out a comparison function that doesn't read the 'args' structure 
This is one small step in "libifying" pdiff which will make it
easier to share this code inside cairo's test suite.
