All painting commands except SetClipRect are shifted by scroll offset
before command list execution. This change removes scroll offset
translation for sample/blit corner commands in
`PaintableWithLines::paint` so it is only applied once in
`CommandList::apply_scroll_offsets()`.
Currently, these only work when there are no CSS transforms (as the
stacking context painting is not set up to handle that case yet). This
is still enough to get most chat/comment markers working on GitHub
though :^)
The WebAssembly spec never relies on host system information, like
size_t. For consistency's sake, we should stick to the usage of u32's
instead of size_t's. This didn't cause issues before because
LEB128-encoded u64's are a superset of LEB128-encoded u32's.
...and use a different color name until a (relatively harmless) bug
writing fully-opaque frames to an animation that also has transparent
frames is fixed. (I've had a local fix for that for a while, but
I'm waiting for #24397 to land.)
Download files to a temporary location, then only move the downloaded
file to the real location once the download is complete. This prevents
CMake from being confused about partially-downloaded files, e.g. if
someone presses ctrl+c in the middle of a download.
Note the GN build already behaves this way.
- Less allocations
- Optimization pass that skips unnecessary sample/blit corner commands
could be more effecient by ignoring corner radius clipping for empty
painting commands
Both page target bitmap and mask bitmap are always BGRA8888, so we can
use `get_pixel<StorageFormat::BGRA8888>` and
`set_pixel<StorageFormat::BGRA8888>` to avoid branching by not
checking a bitmap format.
The if statement in the dispatch implies we are in the idle state, so of
course the active time will always be undefined. If this was cancelled
via a call to cancel(), we can save the time at that point. Otherwise,
just send 0.
This means that userspace breakpoint traps no longer panic the kernel.
This also causes us to no longer panic on failed assertions in userspace
when using gcc, as gcc compiles __builtin_trap to breakpoint
instructions on RISC-V.
I saw a null pointer dereference here on GitHub once, but don't know how
to reproduce, or how we'd get here. Nevertheless, null-checking the
navigable is reasonable so let's do it.
...that maintains a list of allocated execution contexts so malloc()
does not have to be called every time we need to get a new one.

This patch fixes two issues:
- Animation events that should go to the target element now do
(some were previously being dispatched on the animation itself.)
- We update the "previous phase" and "previous iteration" fields of
animation effects, so that we can actually detect phase changes.
This means we stop thinking animations always just started,
something that caused each animation to send 60 animationstart
events every second (to the wrong target!)
We enqueue a microtask for this readable stream AO, and the methods that
we call from the chunk steps manipulate promises. As such, we need to
enable callbacks for the entire microtask's temporary execution
context.
