* Major refactor of display.js queue to assume async rect processing in order to accommodate threaded decode or udp
* QOI lossless decoder on worker threads using WASM
* rfb.js class to provide frame_id and rect counts per frame

* KASM-2090 work around for incomplete webp images when there are lots of concurrent users on a single session. Unknown root cause, work around will in most cases keep the connection alive.
* KASM-2041 auto scale high res mobile - Browsers typically set a scale ratio for high resolution screens, so everything isn't tiny. This mostly works well, but results in a super low resolution for the remote display. This feature detects low resolutions where the browser is doing scaling and adjusts the scale backwards to reach a more reasonable resolution. This typically only happens on modern phones.
This is what the browser wants so it avoids having to spend time
converting everything. Unfortunately it usually means the server instead
needs to convert it for us, but we assume it has more power than we do.
The code that used these were removed in the following commits:
* 9ff86fb718 (RFB._mouse_arr)
* bb6965f2e6 (old_requestAnimationFrame)
* 490d471c53 (Display._c_forceCanvas)
Internet Explorer seems to flag images as loaded prematurely, which
can result in rendering bugs. We can detect this by looking at the
dimensions though.
Commit 6e7e6f9 stopped the function from running if width or height was
zero, this commit reverts that change. This commit also makes the
resulting canvas 0x0 if autoscale is called with zero. By adding this
special case we can avoid division by zero in the calculations.
* Change copyright header
This updates the copyright header to say "The noVNC Authors". People
who previously had copyright listings are now under the AUTHORS file.
With high DPI systems we can end up with a container with a size that
is not an integer number of CSS pixels. Make sure we can handle those
cases by allowing a fractional size for the output canvas. Framebuffer
size and viewport coordinates are still restricted to integer dimensions
though.
Based on initial patch by Alexander E. Patrakov.
Always use the shorthand notation if the function is a method of an object or class `{ foo() { ... } }` or `class bar { foo() { ... } }`
unless it's a callback in which case you a fat arrow function should be used `{ cb: () => { ... } }`
Use normal properties with JavaScript setters and getters instead of
our homegrown stuff.
This also changes the properties to follow normal naming conventions.
