Sciter 4.2: support of “Acrylic” theming

On Windows 10 – Windows build 1803 and above.

Acrylic theming is enabled on windows having:

<html window-frame="extended" window-blurbehind="dark|light|ultra-dark|ultra-light">

Following CSS variables are added by the engine:

var(window-accent-color) – accent color calculated by Windows from desktop background image;

– accent color calculated by Windows from desktop background image; var(window-border-width) – window decoration width.

A bit of technical details:

On Windows 10 Sciter v 4.2 will use WS_EX_NOREDIRECTIONBITMAP window style on all windows. It means that Sciter will draw directly to desktop’s DirectComposition visual tree – even faster drawing.
