The bitmap and image handling interfaces have changed within NetSurf
and the webp image handling has not been fixed up appropriately to
cope.
After discussion with the other developers it has been decided that
the webp support is not worth the necessary development effort to
rewrite and maintain.
The webp format is not in wide usage and Mozilla, Microsoft and Apple
have not adopted it. This means the removal will not adversely impact
NetSurf.

The about dialog box construction was awkward and brittle using
several depricated interfaces. This changes it to use a more generic
dialog creation and uses the response API to simplify click
processing.
It would be even better to use the gtk about dialog but that is a more
invasive change.
Changes the way message files are generated to be driven by make as
rules rather than from explicit macro calls causing their regeneration
every build.
A secondary benefit is that errors in message generation actually stop
the build instead of being ignored
Each frontend will require its filter settings updated to avoid
getting the default message filter of "any". Initially gtk has been
adapted as proof of concept.
The content thumbnailers for each frontend were being provided the
contents url. This was only ever used to call the urldb thumbnail
setting API.
This changes it so the single callsite that passed a valid url adds
the bitmap to that url itself in desktop_history.c instead of forcing
every frontend to require the urldb API.
Additionally the old API could pass the url as NULL which was causing
asserts where this was not an expected parameter value. Because of
this this fixes bug #2286 which was also present in the monkey
frontend as both called nsurl_access() on the url without the NULL
check and caused an assertion.
The size hints given were insufficient for gtk to open the window at a
sensible size or position. This fixes it to open with a default
640x480 size which is a reasonable compromise.
The gtk3 ui builder file was completely reconstructed from fresh as it
was broken and was not working.
The XDG spec allows for software to specify how it is executed and
presented in a graphical environment by using a desktop file
http://standards.freedesktop.org/desktop-entry-spec/latest/
This version is taken from my Debian packaging but should be useful
for other operating systems.
By hiding all but the form selection menu option structure from code
outside of render this reduces the API to the absolute minimum to
support this feature.
