this implies that we need to make sure the property are initialized in
order so that constant properties that depends on other constant properties
are correctly computed
The pass must be done at the begining so that synthetised property don't
become public, and also so that analyses pass can use the public api information
- Mark builtin properties that are modified by the native code as output
- Record wether the property is set by code in the .60
- Add a field that will tell us if a property binding is constant
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.
since the layout now sets an explicit width and height, we check the priority
to see the difference between something explicitly set, and something set by the layout
Instead of using a solve_layout function in the component, use property to hold
a layout cache.
This commit only implement the GridLayout and only the interpreter part
The item tree is intended to be initialized with pointers to the item
vtables, which are implemented using data relocation records that
resolve to the symbols exported by the sixtyfps_cpp shared library.
On windows, according to
https://docs.microsoft.com/en-us/cpp/c-language/rules-and-limitations-for-dllimport-dllexport?view=msvc-160
such data relocations are not supported, so this patch implements the
fallback through getter functions.
The function that initialize all the bindings is huge, and its framz size is
too big. Put each binding evaluation in its own function seems to help
to avoid the stack overflow
Hopefully fixes#133
