* ext/gd/tests/bug45799.phpt: tweak to work with external gd.
The expected output from this test contains an extra newline with
gd-2.3.3 from the system (Gentoo). Adding a whitespace wildcard takes
care of it, and the test still passes with the bundled version of gd.
* ext/gd/tests: external gd-2.3.3 compatibility.
Support for the legacy "gd" image format was removed from gd-2.3.3
upstream:
https://github.com/libgd/libgd/blob/master/CHANGELOG.md#233---2021-09-12
Several tests for the gd extension utilize that format, and naturally
fail when gd-2.3.3 from the system is used. This commit skips those
tests when the version of gd is at least 2.3.3.
* ext/gd/tests/bug73159.phpt: skip with external gd >= 2.3.3
This test uses the imagegd2() function to check that
https://github.com/libgd/libgd/issues/289
is fixed. When an external gd without support for the "gd" format is
used, no error is thrown, but a nonsense result is printed: this is
normal. The corresponding upstream test is disabled in that situation;
it's not expected to work.
This commit skips the corresponding PHP test under the same
circumstances to fix a test failure with external gd >= 2.3.3.
* ext/gd/tests/bug73155.phpt: skip with external gd >= 2.3.3
This test uses the imagegd2() function to check that
https://github.com/libgd/libgd/issues/309
is fixed. When an external gd without support for the "gd" format is
used, no error is thrown, but a nonsense result is printed: this is
normal. The corresponding upstream test is disabled in that situation;
it's not expected to work.
This commit skips the corresponding PHP test under the same
circumstances to fix a test failure with external gd >= 2.3.3.
* ext/gd/tests/bug73157.phpt: skip with external gd >= 2.3.3
This test ensures that the third (chunk_size) parameter to imagegd2()
is respected when a fourth parameter is also given. However, when an
external gd without support for the "gd" format is used, the call to
imagegd2() does not really work at all. It doesn't fail, but it
produces an "image" with a nonsense chunk size.
To avoid failures when an external gd >= 2.3.3 is used, we skip the
test entirely in that case.
* ext/gd/tests/bug77973.phpt: accept lowercase "Invalid"
This test fails with an external gd because the test expects "Invalid"
where upstream gd says "invalid". This commit tweaks the expected
output to accept an arbitrary character in the i/I position.
* ext/gd/tests/bug39780_extern.phpt: update for external gd-2.3.3.
Since there are no CI runs with external gd, I can only assume that
this test has fallen out-of-date due to changes in PHP itself. I've
tweaked the expected output (only slightly) so that the test passes
with both gd-2.3.2 and gd-2.3.3.
* ext/gd/tests/bug66356.phpt: update expected output for external gd.
Newer (external) versions of GD start their error messages with
lowercase characters, whereas this test is expecting them in
uppercase. A single-character wildcard now supports both formats.
* ext/gd/tests/imagegd_truecolor.phpt: skip with external gd >= 2.3.3.
This test uses the imagegd() function, but the "gd" format has been
disabled by default in upstream gd-2.3.3. We still get some kind of
image data back from the call to imagegd(), but its "signature",
"truecolor", and "size" no longer match the expected values. This
commit skips the test when an external gd >= 2.3.3 is used.
* ext/gd/tests/createfromwbmp2_extern.phpt: update for external gd-2.3.3.
* ext/gd/tests/libgd00086_extern.phpt: update for external gd-2.3.3.
Since there are no CI runs with external gd, I can only assume that
this test has fallen out-of-date due to changes in PHP itself. I've
tweaked the expected output (only slightly) so that the test passes
with both gd-2.3.2 and gd-2.3.3.
* ext/gd/tests/bug77272.phpt: update expected output for external gd.
Newer (external) versions of GD start their error messages with
lowercase characters, whereas this test is expecting them in
uppercase. A single-character wildcard now supports both formats.
* ext/gd/tests/bug77479.phpt: update for newer external gd.
This test fails with gd-2.3.3 (at least) due to minor capitalization
and whitespace issues. We add some wildcards to account for the
difference.

We port the upstream fix[1], and also revert commit a3383ac3d7[2] which
is now obsolete, and also not part of libgd. Especially the change to
gd.png.c was at best a half-baked optimization.

Propagating lossless conversion from libgd to our bundled gd.
Changing "quantization" to "quality" as in libgd.
Adding test.
IMG_WEBP_LOSSLESS is only defined, if lossless WebP encoding is
supported by the libgd used.
Closes GH-7348.
Some AVIF image generators didn't include the PixelInformationProperty
(pixi), even though strictly speaking they should. In v0.9.2, libavif
began requiring this. Let's disable it so we can read those images too.
We also remove xfail from test on FreeBSD.
Closes GH-7253.
This test recently started failing on Cirrus CI, possibly after
a libavif update.
Disable it until the issue has been investigated, to avoid an
always failing job.
Thanks to Joe Drago for help with the AVIF detection code.

Closes GH-7091.
This backports avif support from upstream libgd into bundled libgd
and exposes the functionality through new imagecreatefromavif()
and imageavif() functions.
Closes GH-7026.

The function accepts a bool since PHP 8.0, so it should also return
a bool to keep things consistent.
Furthermore a null return from this functions is not possible.
This deprecates passing null to non-nullable scale arguments of
internal functions, with the eventual goal of making the behavior
consistent with userland functions, where null is never accepted
for non-nullable arguments.
This change is expected to cause quite a lot of fallout. In most
cases, calling code should be adjusted to avoid passing null. In
some cases, PHP should be adjusted to make some function arguments
nullable. I have already fixed a number of functions before landing
this, but feel free to file a bug if you encounter a function that
doesn't accept null, but probably should. (The rule of thumb for
this to be applicable is that the function must have special behavior
for 0 or "", which is distinct from the natural behavior of the
parameter.)
RFC: https://wiki.php.net/rfc/deprecate_null_to_scalar_internal_arg
Closes GH-6475.
If the string is too short, we should treat this the same way as
an unrecognized image type. This function should be usable to
determine whether something is a valid image without doing any
checks beforehand.
Currently we treat paths with null bytes as a TypeError, which is
incorrect, and rather inconsistent, as we treat empty paths as
ValueError. We do this because the error is generated by zpp and
it's easier to always throw TypeError there.
This changes the zpp implementation to throw a TypeError only if
the type is actually wrong and throw ValueError for null bytes.
The error message is also split accordingly, to be more precise.
Closes GH-6094.
The color resolution is expected in bits 4-6 of the packed fields byte
of the logical screen descriptor (byte 10 of the GIF data stream),
according to the specification[1], section 18.
