Rework ViewElement to open new usages #809

Closed TimLariviere closed 3 years ago

TimLariviere commented 3 years ago

As part of the allocations reduction process, I'm reworking the ViewElement class to become an interface IViewElement. This will allow for different implementation such as ComponentViewElement (see https://github.com/TimLariviere/Fabulous/issues/25 for more information).

In this example, ComponentViewElement would drastically reduce the number of allocated ViewElement at each update.

Introduced Registrar and DynamicViewElementHandler types. Those will avoid having to store targetType, create, update and updateAttachedProperties inside each DynamicViewElement instances, reducing the memory footprint of 1 DynamicViewElement.

So this should have a great impact on the memory allocation due to the sheer numbers of DynamicViewElement instantiated throughout the life of an application.

This PR also reworks the way we print some debug info to the console, by using a built-in tracing tooling. This will help fix #307
