[Development] QtWebEngine embedded switches

[Johannes Pointner]

Hi all,

I'm playing around with a few Chromium settings on an i.MX6 board and
wanted to ask if some of the flags which are set by
"useEmbeddedSwitches" are still necessary:

- kDisableGpuShaderDiskCache:
This one was removed from the Android browser startup flags with the
following commit in 2015:
https://chromium.googlesource.com/chromium/src.git/+/e6f2605e3a3fa107ef00ba1033a28246db239734%5E%21/

- kDisable2dCanvasAntialiasing:
This one was removed from the Android browser startup flags with the
following commit in 2013:
https://chromium.googlesource.com/chromium/src.git/+/6e7058c16d8dcff3af27f207abeac9f5923eb7d1%5E%21/

As far as I was able to check these settings they hadn't any negative
impact if enabled.

Thx,
Hannes
