# Pixman versioning scheme
|
|
|
|
|
#
|
|
|
|
|
# - If the changes don't affect API or ABI, then increment pixman_micro
|
|
|
|
|
# - If API is added, then increment PIXMAN_MINOR, and set MICRO to 0
|
|
|
|
|
#
|
|
|
|
|
# - If you break ABI, then
|
|
|
|
|
# - In the first development release where you break ABI, find all instances of
|
|
|
|
|
# "pixman-n" and change it to pixman-(n+1)
|
|
|
|
|
#
|
|
|
|
