Subject: Make the test program test something useful.
X-Git-Tag: pixman-0.9.4~133
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e36c6a5eb4cc89da8cf8d66dd45d02b75584e243;p=platform%2Fupstream%2Fpixman.git

Make the test program test something useful.

Also add a check that the public image struct is big enough to contain the
private union.
