Support for any font #266
Description
Description
Today alphaTab only supports some default fonts and can only do an approximate fallback to other fonts. Reason is mainly that the font sizes are needed in the WebWorker which currently does not have any possibility of measuring the font sizes. This is often needed for correct positioning of elements.
Possible Solutions
Before initiating the rendering in the worker, the UI thread needs to calculate the sizes of the configured fonts for measuring (e.g. using HTML5 canvas). We must consider that the configured fonts might be web fonts that are not yet available and hence we must use the font-detection system that is also used for alphaTab.
