\core\local\cli\shutdown::script_supports_graceful_exit();
Sets up interception of exit signals and keep the script running.
\core\local\cli\shutdown::should_gracefully_exit();
Use this to check whether you should exit, often inside a long running loop.
Some browsers, notably Firefox, do not return the computed style for
background colour in a computed RGB format. Instead they return the RGBA
where the alpha channel is set to fully transparent.
To solve this we need to work up the hierarchy and compute the
background colour for each parent node until we reach full alpha (1).
We can use a standard calculation to approximate the value for the
resultant element background by multiplying the alpha of the current
transparent (or semi-transparent) node with the R, G, or B channel in
question, and that of the parent node's background colour.
There are cases where this will not be 100% accurate - notably where
there is some additional content in addition to the parent background,
but this gives us a reasoable approximation for the majority of cases.
Additionally the code has never considered the full set of node content
when calculating this information.
If 'unix' is the first element of the stream_get_transports() result
array, array_search() will return `0` as index result which, when
negated, will result as true.
There are various places where it's not guaranteed that the
variable being used is array, and instead, can be null, bool, int...
We need to check that because php74 warns about it.
Where possible we have used the coalesce operator as
replacement for isset() ternary operations.
Trying to use values of type null, bool, int, float or resource as an
array (such as $null["key"]) will now generate a notice. This does not
affect array accesses performed by list().
