The fnmatch patch that was added in 6de6dff is reverted because it is
not clear why it is necessary, as discussed in #9206.
This also removes diffutils from the list of ports missing descriptions
as it no longer has any patches.
Three optimizations are applied:
1. If the list of vertices to clip is empty, return immediately after
clearing the output list.
2. Remember the previous vertex instead of recalculating whether it is
within the clip plane.
3. Instead of copying and swapping lists around, operate on the input
and output lists directly. This prevents a lot of `malloc`/`free`
traffic as a result of vector assignments.
This takes the clipping code CPU load from 3.9% down to 1.8% for
Quake 3 on my machine.
This keeps us from accidentally overwriting an already set region name,
for example when we are mapping a file (as, in this case, the file name
is already stored in the region).
The existing code looks innocently correct, implementing the following
step:
3. If IsCallable(func) is false, set func to the intrinsic function
%Object.prototype.toString%.
as
return ObjectPrototype::to_string(vm, global_object);
However, this misses the fact that the next step calls the function with
the previously ToObject()'d this value (`array`):
4. Return ? Call(func, array).
This doesn't happen in the current implementation, which will use the
unaltered this value from the Array.prototype.toString() call, and make
another, unequal object in %Object.prototype.toString%. Since both that
and Array.prototype.toString() do a Get() call on said object, this
behavior is observable (see newly added test).
Fix this by actually doing what the spec says and calling the fallback
function the regular way.
For inline-blocks and inline replaced elements, we previously fell into
a code path that tried to find a corresponding line box fragment to
invalidate. However, we don't need to do any of that, all we need to do
is get the absolute rect from our paintable, and invalidate that.
This makes CRC2D invalidations happen immediately instead of as a side
effect of some other invalidation.
