This is a reimplementation of draw_triangle that manages without
floating point arithmetic.
It's most important property, compared to the previous implementation is
that rotating the same triangle 90 degrees won't drastically change the
appearance of that triangle. (it did before)
|
|
This doesn't actually change anything in appearance, but it lays the
groundwork to have these graphics scaling compatible once the window
backstores support that.

Used by Google seemingly almost all around account sign in and
management. The modern sign in page has this near the beginning:
```html
<base href="https://accounts.google.com">
```
All of the XHRs performed by sign in are relative URLs to this
base URL. Previously we ignored this and did it relative to the
current URL, causing the XHRs to 404 and sign in to fall apart.
I presume they do this because you can access the sign in page
from multiple endpoints, such as `/ServiceLogin` and
`/o/oauth2/auth/identifier`

It's called srcElement instead of srcTarget.
Required by w3school's search focus handler.
|
|
We simply return "/dev/tty", since it always refers to the controlling
terminal of the calling process.

I missed this in a25c5d8. Thanks to Idan for noticing :^)

The AA painter will actually draw the dots as circles, which is
how other browsers handle this.
|
|
This adds simple dotted lines (horizontal/vertical only for now).
There's a little number fudging added in to make sure the final
dot is always drawn at the endpoint (for lines with at least a
handful of dots).
|
|
As usual, we just define these based on the given integer size itself.

Previously we would not set m_selected_index or the editor's text value
when calling set_selected_index.
|
|
This allows an Application without a window to listen for theme changes.
|
|
This patch adds a helper to ComboBox allowing it to clear the current
selection and show a blank editor.

* Always return 0 if `WNOHANG` is specified and no waitable child is
found, even if `wstatus` is null.
* Do not return 0 if the child is continued. Treat it the same way as
all the other states.
Refer to the RETURN VALUE section of the POSIX spec:
https://pubs.opengroup.org/onlinepubs/9699919799/functions/wait.html
|
|
Like other systems, we can encode the continued state with 0xffff in the
status value. This is needed for some ports.

Before, when holding at a location in the gutter until the scrubber
reached that location, the gutter would stay tinted, even after the
target was reached, and the scrubber didn't move any more; only
stopping when the pointer was moved.
|
|
Previously clicking in the gutter of an activated scrollbar while
holding shift would crash on the removed VERIFY.
|
|
Previously, this was slightly off and not doing what the spec comment
above asked for. This led to really small values for x_step and
y_step, making the `backgrounds.html' example use crazy amounts of
CPU whist painting.
|
|
This avoids excessive over painting.

From the spec:
> This property previously accepted the values optimizeSpeed and
optimizeQuality. These are now deprecated; a user agent must accept
them as valid values but must treat them as having the same behavior
as pixelated and smooth respectively, and authors must not use them.

It's probably not in 1:1 as spec says, as it wants us to first upscale
the image to the nearest integer and then downscale it bilinearly.
But this mode still falls into the general description of the value:
> The image is scaled in a way that preserves the pixelated nature of
> the original as much as possible, but allows minor smoothing instead
> of awkward distortion when necessary.
Also, this way we don't have to allocate the memory just for the integer
scale. :^) :^)

If you wanted to upscale an image, you had two options:
- use Nearest Neighbor: it's probably a good choice. The image stays
sharp.. unless you aren't using integer scales.
- use Bilinear blending, but this on the other hand, doesn't handle
upscaling well. It just blurs everything.
But what if we could take the best of both of them and make the image
sharp on integers and just blur it a little when needed?
Well, there's Smooth Pixels!
This mode is similar to the Bilinear Blend, with the main difference
is that the blend ratio is multiplied by the current scale, so the blur
on corners can be only 1px wide.
From my testing this mode doesn't handles downscaling as good as the
Bilinear blending though.

This method is needed in subclasses of PaintableBox to do
border-radius clipping.
|
|
|
|
This is a helper class for clipping the corners off a element.
This works in a similar way to how (outline) borders are painted.
The steps are:
1. A small bitmap that fits only the corners is allocated
2. The corners are painted into the bitmap
3. The existing pixels (where the corners will be painted)
are copied using the (inverse) corner bitmap as a mask
(done before the element is painted)
4. The element is painted
5. The areas outside the corner radii are restored
Like with the borders, this only requires allocation on the first
paint.
|
|
This will allow the same bitmap to be shared between border,
background, and various other corner clipping code.
|
|
This is required to do some painting tricks in LibWeb, this has to be
added to the painter so it can apply the paint translation first.
|
|
Implement parsing of rgb(..) and hsl(..) in both the modern level 4
syntax without commas, and the legacy syntax with commas.
The parser accepts non-integer numbers but rounds to integer values
for now.
