Whenever `gdImage*Ptr()` calls `gdImage*Ctx()` and the latter fails, we
must not call `gdDPExtractData()`; otherwise a double-free would
happen. Since `gdImage*Ctx()` are void functions, and we can't change
that for BC reasons, we're introducing static helpers which are used
internally.
We're adding a regression test for `gdImageJpegPtr()`, but not for
`gdImageGifPtr()` and `gdImageWbmpPtr()` since we don't know how to
trigger failure of the respective `gdImage*Ctx()` calls.
This potential security issue has been reported by Solmaz Salimi (aka.
Rooney).
This makes the code better readable in the sources, and we get syntax
highlighting in the generated HTML wherever we want it (i.e. not necessarily
always as with `-hl all`).
This changeset imports documention for gdImage to gdImagePng*() into
Natural Docs. Documention is based on the text of the original
manual, version 2.0.36 but adapted to better suit the format.
Subsequent changesets will introduce docs for subsequent manual
entries.
naturaldocs, when present, is invoked by bootstrap.sh. The completed
manual will be in docs/naturaldocs/html/index.html. It can also be
explicitly invoked by running docs/naturaldocs/run_docs.sh.
This change also removed docs/naturaldocs/project/Menu.txt, since it
currently contains no non-generated content and is prone to introduce
noise into the changeset.
