--- Comment #5 from Caolán McNamara <caolanm at redhat.com> ---
yeah, its that gradient XOR. I can at least parallelize our xor-in-cairo hack
with https://gerrit.libreoffice.org/#/c/64111/ which will make it faster,
depending on the number of threads available, but maybe alg knows a better way
to tease the drawinglayer down a different path that avoids that xor in the
first place ?
