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.

Previously, we would compact the buffer (moving unread data to the
start of the buffer) as follows:
- after processing a message, if there are zero unread bytes, just reset
the indices for first and last unread byte to zero
- else, if at least 1/8th of the buffer is used, copy remaining data to the beginning of the buffer
The second option is never actually necessary, as before inserting new data
into the array, we already check if there's enough free space, and
compact the buffer first if necessary. So we've been doing a lot of
copies that weren't actually needed. Let's not do that any more.
