# Pixman versioning scheme
#
# - The git version must at all times have an odd MICRO version
# number.
#
# - If you add API, increment the MICRO version to the next largest
# odd number.
#
# - If you release a version that contains new API, then increment
# MINOR and set MICRO to 0.
#
# - If you release a new version that does not contain new API, then
# increment MICRO to the next even number.
#
# - After doing a release, increment MICRO again to make the version
# number in git odd.
#
# - If you break the ABI, then
#
# - increment MAJOR
#
# - In the first development release where you break ABI, find
# all instances of "pixman-n" and change them to pixman-(n+1)
#
# This needs to be done at least in
# configure.ac
# all Makefile.am's
# pixman-n.pc.in
#
# This ensures that binary incompatible versions can be installed
# in parallel. See http://www106.pair.com/rhp/parallel.html for
# more information

dnl GCC 4.2 when compiling with -msse will generate SSE instructions
dnl on its own. This means anything compiled with -mss can only be
dnl run after a runtime check for SSE. Unfortunately, since we still
dnl need to support MMX-but-not-SSE (such as the OLPC), this means we
dnl can only use SSE when compiling for x86-64 (where SSE is always
dnl supported).
