Thank you for your advise.
I have suggested to fix this problem in App side.
Thank you.

Pixman code was originally a part of Xorg server, which only needs and
uses 16.16 fixed point format:

Some of the 16-bit limitations are already removed. Some of them are
still there. Fixing all of the remaining 16-bit assumptions in one go
(and actually confirming that the problems are indeed fixed) may
require a non-trivial amount of work.
But what exactly are you trying to do and how do you hit this
PIXMAN_MAX_INT limitation? A "realistic" approach is to try fixing
problems as they are discovered and extend the pixman test suite
to make sure that these problems don't show up again.
I may be wrong, but pixman users seem to generally prefer workarounding
these problems (for example, by splitting rendering into smaller
chunks) instead of reporting bugs and/or complaining. So the issue
is not getting enough attention.
