Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc.
If possible, make the script source available online and provide
an URL to it here. Try avoid embedding huge scripts into the report.

Description:
------------
Using the las version of Graphical Library PHP_GD2 leads to display
images which are only partially filled when using the function
ImageFillToBorder.
It looks like only the upper part of the zone which should be filled
gets the selected color.
The problem doesn't appear when using le 4.3.5 version of php_gd2.
