99d280a927 LibGfx/WebPLoader: Relax vp8x / vp8l alpha check 
The check from 0805319d1e is too strict for animated images: It's
possible that an animation has alpha, but a frame doesn't.

(For example, if the animation is 10x10 pixels, but one frame updates
just 1x1 pixels. But even a full-sized frame could just not have alpha.)

If the VP8X header claims that the animation has alpha, we could check
that at least one frame has alpha, but for now we just don't do any
checking for animated images.

b8d18ebcf7 LibWeb+WebContent: Change event loop to synchronously paint next frame 
...instead of scheduling repaint timer in PageClient.

This change fixes flickering on Discord that happened because:
- Event loop schedules repainting by activating repaint timer
- `Document::tear_down_layout_tree()` destroys paintable tree
- Repaint timer invokes callback and renders an empty frame because
  paintable tree was destroyed

e806136116 LibWeb: Refresh clip and scroll state only when needed 
Although refreshing is cheap, it was performed before each hit-testing
and was 2-4% in profiles on Discord and Twitter.

Now clip and scroll states are refreshed only if scroll offset has
changed.

d6297ec074 LibWeb: Cast to the correct type in Element::auto_directionality() 
Previously, we always cast to a HTMLInputElement when getting the value
of an auto directionality form associated element. This caused
undefined behavior when determining the directionality of an element
that wasn't a HTMLInputElement.

This means that relative width values are now correctly resolved when
calling `getComputedStyle()`.

7d192ed8c1 LibWeb: Don't crash on clicking a label with an associated text input 
Previously, we assumed that all label control paintables were of type
`LabelablePaintable`. This caused a crash when clicking on a label with
a text input control.

1fa7235fec LibWeb: Add Implement GainNode interface 
As with all other current audio nodes we still need to wire up the
inputs and outputs so it can be properly used in an audio context - but
this is enough to implement the public IDL interface.

dacba5e610 Tests/LibWeb: Initialize 'arrayBuffer' to an UInt8Array 
This initializes 'arrayBuffer' to an UInt8Array so that we can
manipulate the contents of 'arrayBuffer'. The test verifies that the
internal buffer is an ArrayBuffer.

Also:
* Correct comparison in test so that we compare arrayBuffer to
  arrayClone, not to itself.
* Remove FIXME, this outputs [object ArrayBuffer] in Firefox and Chrome
  too.

8988dce93d LibGfx: Add early bounds checking to accumulate_non_zero_scanline() 
Nonzero fills are much more common (as the default fill rule), so if
this does result in any speed-up it makes sense to do it here too.
