When compacting the receive buffer, we should only copy the bytes
between _rQi and _rQlen (the index of the first unread byte, and the
next write position).
Previously, we copied everything for _rQi up untill the end of the
buffer.
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.
These are harmless and really only for debugging. So remove them
as they tend to trick people in to thinking something is wrong.
We already print the entire server pixel format earlier anyway in
case we need the details.
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.
It is not necessary as Websock.flush() is guaranteed to succeed and
give us some space. It also remove the call to _fail(), which was
invalid at this place as clientCutText() is not a method on RFB.
We accidentally removed the code updating the data index in 8a189a6,
resulting in the decoder newer consuming any data. So the data would
be parsed as the next rect, causing weird errors.
Previously scrollbars were disabled on all touch devices. This meant
that they were disabled on Windows when touch was detected. Windows does
in fact have useful scrollbars even in touch mode. Fixes Issue #1172
