# PROBLEMS WITH SKIA DEBUGGING?? READ THIS...
#
# The debug build results in changes to the Skia headers. This means that those
# using libskia must also be built with the debug version of the Skia headers.
# There are a few scenarios where this comes into play:
#
# (1) You're building debug code that depends on libskia.
#   (a) If libskia is built in release, then define SK_RELEASE when building
#       your sources.
#   (b) If libskia is built with debugging (see step 2), then no changes are
#       needed since your sources and libskia have been built with SK_DEBUG.
# (2) You're building libskia in debug mode.
#   (a) RECOMMENDED: You can build the entire system in debug mode. Do this by
#       updating your buildspec.mk to include TARGET_BUILD_TYPE=debug
#   (b) You can update all the users of libskia to define SK_DEBUG when they are
#       building their sources.
#
# NOTE: If neither SK_DEBUG or SK_RELEASE are defined then Skia checks NDEBUG to
#       determine which build type to use.
