[GTK] Do not depend on resources provided by the GNOME icon theme

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Adrian Perez]

As per the discussion in bug #186638 (comments 15 to 17), we should NOT
depend on gnome-icon-theme being installed, and therefore the resources
built as part of WebKitGTK+ should include a copy of the needed icons.

[Michael Catanzaro]

This entails fixing the following crash:

STDERR: 
STDERR: warning: core file may not match specified executable file.
STDERR: g_bytes_get_size: assertion 'bytes != NULL' failed

We currently have the following code:

static Ref<Image> loadMissingImageIconFromTheme(const char* name)
{
    // ...
    if (iconInfo) {
        // Is the icon installed?
        return WTFMove(icon);
    }

    return loadImageFromGResource(name);
}

That's currently incorrect. But we won't need any code changes if fixing this bug. (It is surely preferable to lookup the icon at runtime, and only fall back to an embedded resource if missing.)

Note I've added a test expectation against this bug, for fast/hidpi/broken-image-icon-very-hidpi.html.

Please, do not forget the media control icons if you bundle them

The only test filed under this bug at this moment is:

The test has been consistently crashing for the last 4000 revisions with the following stacktrace (debug crash-log):

So the issue seems to be that resource "[e-mail]" is missing.

The style-checker issue seems a bit like a false positive. It is possible to
workaround it by appending to the list one item at a time, for example:

  set(WebKitResources "")
  list(APPEND WebKitResources "<file alias=\"css/gtk-theme.css\">gtk-theme.css</file>\n")
  list(APPEND WebKitResources "<file alias=\"images/missingImage\">missingImage.png</file>\n")
  list(APPEND WebKitResources "<file alias=\"images/missingImage@2x\">[e-mail]</file>\n")
  ...

We can either land manually to go around the false positive, or if you feel like
reworking this a bit as suggested to avoid the style checker complaints, then it's
fine to use the commit-queue :)
