This API does:
- Take a Utf8View
- Take the starting point on the baseline as its input coordinate
This API does not:
- Align the text
- Wrap the text
- Elide too-long text into "..."
We now support generating top-left submatrices from a `Gfx::Matrix`
and we move the normal transformation calculation into
`SoftGPU::Device`. No functional changes.
We were transforming the vertices' normals twice (bug 1) and
normalizing them after lighting (bug 2). In the lighting code, we were
then diverting from the spec to deal with the normal situation, which
is now no longer needed.
This fixes the lighting of Tux in Tux Racer.
This reverts commit 2b2915656d.
While this adjustment is bogus, it is currently responsible for putting
CenterLeft aligned scalable text in the right position.
This is going to take a bunch of work to get right.
We've gotten ourselves into a bit of a mess by mixing pixel and point
sizes in multiple places. Step one towards getting out of this mess
is adding explicit accessors for the unit you're trying to fetch.
The core of the issue comes from bitmap fonts storing integer pixel
sizes and scaled (TTF) fonts storing float point sizes.
This replaces the usage of `rounded_int_rect`, whose name did not
accurately reflect the rounding operation happening. For example, the
position of the rect was not rounded but floored, and the size was
pulled through `roundf` before casting to `int` which could result in
inadvertent flooring if the resulting floating point could not exactly
represent the rounded value.
There was an off-by-one bug in `Painter::do_draw_scaled_bitmap` where
the last column and row of the source bitmap would be skipped. This was
especially visible in PixelPaint when zooming in and out on smaller
images.
Instead of the top/left of the pixel, we now use the bottom/right side
of the pixel as a threshold to stop drawing.
There's really no reason to use doubles here, except at the time I
wanted to use doubles everywhere in CSS. I now realize that is
excessive, so everything can be floats instead.
This helps make the overall codebase consistent. `class_name()` in
`Kernel` is always `StringView`, but not elsewhere.
Additionally, this results in the `strlen` (which needs to be done
when printing or other operations) always being computed at
compile-time.
`static const` variables can be computed and initialized at run-time
during initialization or the first time a function is called. Change
them to `static constexpr` to ensure they are computed at
compile-time.
This allows some removal of `strlen` because the length of the
`StringView` can be used which is pre-computed at compile-time.
C++20 provides the `requires` clause which simplifies the ability to
limit overload resolution. Prefer it over `EnableIf`
With all uses of `EnableIf` being removed, also remove the
implementation so future devs are not tempted.
Use different specified radii for the two seperate passes.
The gaussian approximation is not changed to accept two parameters since
the math is not exactly straight forward and therefore something for a
later patch. For now, let's progress!
It isn't sensible to have a negative radius for blurring, so an unsigned
value is the right thing to do here.
Now we have to cast the radius to int a few times when actually doing
the calculations but I'm sure that can be done more intelligently, but
that optimization is a thing for the future.
It looked very goofy for the two different ways of invoking the Filter
to have differently signed arguments.
PBM, PGM, and PPM image loaders are mostly common. The only difference
is how the data is read and the associated magic numbers. The magic
numbers are already made common using the loading contexts. Now make
the implementations common via a class template which accepts the
context to disambiguate.
Much of the code in PBM, PGM, and PPM image loaders is common. The
contexts are nearly identical. Instead of writing multiple contexts,
write 1 with a template argument to pass in the details of the given
format.
When doing viewbox transforms, elliptical always had large arc and
sweep flag set to false. Preserve these flags so they can be set
correctly when applying viewbox transformations.
In testing a particular website (https://www.icpms.com), WebContent
was crashing with infinite recursion in draw_circle_arc_intersecting.
Presumably, radius must be > 0 to paint something, so this trivial
patch simply returns if radius <= 0. The website in question no longer
crashes WebContent.
Currently, disabled text colors are hardcoded. They look good in Default
and light themes, but no so good in dark ones. This PR adds new
variables for all themes to correctly display disabled text.
This matches the rename of RGBA32 to ARGB32. It also makes more sense
when you see it used with 32-bit hexadecimal literals:
Before:
Color::from_rgba(0xaarrggbb)
After:
Color::from_argb(0xaarrggbb)
The ARGB32 typedef is used for 32-bit #AARRGGBB quadruplets. As such,
the name RGBA32 was misleading, so let's call it ARGB32 instead.
Since endianness is a thing, let's not encode any assumptions about byte
order in the name of this type. ARGB32 is basically a "machine word"
of color.
