The previous value made the detection too sensitive and it was very
difficult to scroll precisely. A value of 50 pixels should give similar
behaviour to systems that don't do fine grained scrolling.
This isn't really expected behaviour from a user, i.e. that an extremely
small wheel movement still gives a large scroll event in the remote application.
Add several single and multitouch gestures to simulate various mouse
actions that would otherwise be impossible to perform.
This replaces the old system where you could select which mouse button
a single touch would generate.
The code that used these were removed in the following commits:
* 9ff86fb718477515ede2d6457f06643935d76bcd (RFB._mouse_arr)
* bb6965f2e60c2301dd638383bdc792d1f10af942 (old_requestAnimationFrame)
* 490d471c53b1791398d6c30f0efce54925939f33 (Display._c_forceCanvas)
If too much text is copied in the session, String.fromCharCode.apply()
would crash in Safari on macOS and Chrome on Linux. This commit fixes
this issue by avoiding apply() altogether. Also added test to cover this
issue.
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.
Caps Lock on iOS only trigged key release or key press events.
When it's clicked it would only send keydown, and next time
it would only send keyup and so on. It should send both a key press
and a key release.
Also added the unit tests for macOS since those were missing.

There is no obvious choice what works best here, but this is what
TigerVNC has been doing for years without complaints. Let's follow
them until we get reports that this doesn't work well.
It seems Apple has fixed their buggy keyup events, so remove the
workaround and allow keys to be kept pressed again.
This is a revert of 9e99ce126ca8f6f350fa015c0e58d35103c62f7e.
The standards have unfortunatly caused some confusion between the Windows
key and the original Meta key. Try to handle the common case sanely at least.
Supports both classic cursor type and alpha cursor type. In classic
mode the server can send 'inverted' pixels for the cursor, our code
does not support this but handles these pixels as opaque black.
