partialRenderFinished
Description​
AlphaTab does not render the whole music sheet into a single canvas but rather splits it down into smaller chunks. This allows faster display of results to the user and avoids issues related to browser restrictions (like maximum canvas sizes).
This event is fired whenever one chunk of the music sheet is fully rendered.
Since 1.2.3 the rendering of a chunk needs to be requested via the renderResult method after
a chunk was advertised through the partialLayoutFinished event.
