* 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.
