Text's behavior right now is to clip on a line basis, so with the given
font-size for these two elements, the glyphs aren't shown at all because
the ascent + descent that's use for the clip test is bigger than the
maximum height, despite the actual glyphs fitting.
For now, reduce the font-size slightly to make the glyphs fit.
Let's keep source compatibility and define `drop-shadow-blur` to be a radius.
The CSS spec says that the standard deviation is half of the radius.
We just need to scale again and increase the shadow rect to make sure that no borders are visible.
This replaces the box gradient with a new implementation that
behaves like the HTML Canvas element, by applying a gaussian
blur to the alpha of the rectangle to shadow.
The drop-shadow-blur property is changed to be now just a "level", like
the HTML Canvas shadowBlur property, which is defined to be half of the
standard deviation of the gaussian blur to be applied.
Use a brush instead of color as property type for those theme properties
that can be brushes.
This allows to use gradients for backgrounds for live demonstrations
If `clip` were a similarly created property, then
this would probably look a little nicer in the source code.
The `Clip` element is a little in the way.
This patch tries to improve the ability to convert different kinds of
object literals in an array into a common type. We used to take the
first entry as the "shape" of all elements, which meant that if the
first element was missing a field it would be silently dropped from all
future fields.
Instead, this patch merges the fields.
For regular builds this is done by adding Rust API that allows
registering a font, and for the web the font is installed into the
browser using JavaScript API.
This is an initial approach to just add this ability. It might make
sense to introduce a syntax in the `.60` file to allow for the
registration of fonts and letting the compiler generate code that
performs this embedding and registration automatically.
This allows implementing another sliding puzzle theme feature, the
boldness of the tile number text in the simple theme when the tile is in
the correct position. For the other themes the weight is constant and
it's bold.
More cleanup to follow later: unify the font handle and FontCacheKey
handling, improve the API to allow for the use of symbolic constants
(normal, bold, etc.) instead of the CSS number values.
