Two minor issues:
This script is written in python two which is depreciated, and should be rewritten in python three, but I have so far been successful in not learning python. :-) to simplify debugging I have clarified that it needs a python two interpreter.
This script downloads an old version of mesa (an update may be appropriate), unfortunately the release candidate previously specified is no longer available, so an update to the next released version was made.
Require all SMsgWriter caller to check capabilities
Make the API consisitent by requiring the caller to check what the client
supports before calling any of the write* functions. This avoids the
confusion that the functions might not always do anything.
This is what the protocol requires, rather than sending what the
client specified in the request. This should be the same in practice
except for failures and possibly some races.
Increase range of ComparingUpdateTracker statistics
32 bits are not enough to keep track of all the pixels that might
flow through the system. Expand things to 64 bits, which should cover
all reasonable uses.
There is a range of key codes that are never sent by a real keyboard
and are therefore used by layouts to hide "fake" mappings. Make sure
to only use these as a fallback as some applications get confused
when they see these codes.
We need to check earlier if we are going to send this refresh or
not. Otherwise we send out pings pointlessly, and we also stall
the request loop with a client as we clear the requested region
without actually sending an update message.
because it is not only platform independent
but also allows to override the build date
This helps to make tigervnc builds reproducible
See https://reproducible-builds.org/ for why this is good
Also adds UTC flag, to be independent of timezone.
Also changes JAVA_DATE format to ISO-8601 date format.
Requires cmake-2.8.11+ from 2013
Prevent rendering uninitialized Pixmap contents on X11
The Pixmap is filled in as updates from the server arrive. Before the first full update, it would contain undefined contents, which would be rendered onto the ViewPort.
Clearing the Pixmap is only done on startup and when changing the server resolution, so it's not performance critical.
