Textfield rendering functionality extension.

    Well...

    There is a way to bypass some limitations in html+css rendering.

    I used this thing to make hotspots for VR look the same as in common mode:
    https://github.com/pbakaus/domvas

    It renders styled html code into canvas and lets save it as an image. WIth it's own limitations, yet, I was unable to render pictures into canvas.
    A little layouts with some custom positioned blocks and custom icon fonts worked OK, and text features support is full.

    That script uses the 'drawing a svg with a foreignObject with embedded html code to canvas' method. I'm aware about this possibility of course and tried it already some years ago, but there is a big problem with that - it doesn't work an iOS (due iOS bugs) and so far I remember there were also problems with other browsers - and by this it's unfortunately already dropped out. And hopping for bugfixes in newer iOS releases is illusory ;-).

    Well, i think html2canvas is better option, isn't it?

    This one uses a similar approach as krpano by parsing the DOM and rendering everything manually.


    I will not include any of them into krpano, but I will think about extending the current plugin API to allowing using a custom canvas element that could be directly used for the hotspot rendering. Then such scripts could be used in user plugins.
