Multiple shadows repaint were made because of comparison of records through an interface.
The base interface was replaced by an abstract record.
Another repaint was also sometimes made due to the fact that we didn't take into account the uninitialized pixel ratio.

On the wasm sample, the shadow does not appear anymore (it flickers and goes away):

When tested in wasm we still have delays and changes seem slower.

Well I guess because when resizing the shadows the canvas must be invalidated at each size...
Without this PR be aware that the rendering was working because of the combination of 2 bugs.

I will try to squash some invalidation and do some perf logs to improve shadow rendering when elements/canvas are resizing.

Beware of impressions, when tested in wasm with profiling:

	  <WasmShellMonoRuntimeExecutionMode>InterpreterAndAOT</WasmShellMonoRuntimeExecutionMode>
	  <WasmShellEnableEmccProfiling>true</WasmShellEnableEmccProfiling>

We got the following results:

Without the PR:

profile_without_PR

WITH the PR:

profile_WITH_PR

Roughly 40% increased performance.

This is confirmed by logs made in Debug:
