Unable to run lightning on QT5 browser

[MikePask]

I have been trying to compile a version of lightning that will run on QT5. The issue I currently have is ImageData() is not a constructor. ImageData constructor is not available on this browser, QT5 is similar to safari 7. ImageData constructor appears to be available from Safari 8.

Are you using the canvas2d renderer? And is this line causing the error?

Lightning/src/renderer/c2d/C2dRenderer.mjs

Line 98 in 2e4c829

const imageData = new ImageData(new Uint8ClampedArray(options.source.buffer), options.w, options.h);

Yes I am and that is the line.

https://developer.mozilla.org/en-US/docs/Web/API/ImageData/ImageData is available since Safari 8 but we can try to fallback to createImageData() method, that is available since Safari 4: https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/createImageData

I've added a quick implementation for you to test: https://github.com/rdkcentral/Lightning/compare/feat/c2d-imagedata-fallback if this works we can do a proper implementation
