The glyphs cache only tracked the number of glyphs
in the cache, which isn't very useful when the
glyphs vary in size from a few bytes to dozens of
megabytes. In terms of memory footprint, we are
interested not just in the number of cached glyphs,
but also in the total memory usage.
We now track the pixel-size of each glyph and drop
as many as necessary to fall below the set threshold
which is currently 4 MBs.
There was no performance loss observed after this patch
on a diverse set of documents of all types (if anything,
a very modest performance win was hinted in some cases),
with significant memory reduction in some cases where
dozens of megabytes were previously left stale in the cache.

* from pixman-0.24.4.patch drop:
- Android support config.sub: obsoleted by new upstream autoconf
- configure Mac OS X 10.4 (unsupported) linker warning
- configure getisax Solaris check: it's unclear why this would
give a wrong result on Linux, it certainly does't on Fedora 24...
- __inline__ workaround looks fixed upstream
* drop pixman-0.24.4.android.patch:
obsoleted by new upstream autoconf
* from cairo-1.10.2.patch drop:
- Makefile.win32.common: drop this for now, we don't build
cairo on windows and paths in this patch are still dmake INPATH...
- Android support config.sub: obsoleted by new upstream autoconf
- configure "libpng15" should be obsolete since it's overridden
by png_CFLAGS/png_LIBS anyway
- configure Mac OS X 10.4 (unsupported) linker warning
- cairo-output-stream.c: fixed upstream
- cairo-ft-font.c: presumed obsolete, FcResultOutOfMemory added in 2004
* drop cairo.dlsym.lcdfilter.patch:
FT_Library_SetLcdFilter since 2.3.0 so exists in RHEL 6 baseline (2.3.11)
* drop cairo-1.10.2-oldfontconfig.patch:
RHEL 6 baseline has fontconfig 2.8.0 so 2.2.95 isn't "too new"
* drop cairo-1.10.2.wntmsc.patch:
we don't build cairo on windows currently, and this doesn't apply
* drop no-flto-clang.patch:
fixed upstream
* remove definition of COMPRESS var that appears to be completely unused
