Ishak BELAHMAR a1ed978db9 kete: Handle variable stroke pressure
This is a first implementation of variable stroke pressure. It is based
on a set of individual-width-variable strokes. The ideal implementation
should convert the variable-stroke-width path into an outlined shape.

Benjamin Tissoires 9e85b4d248 flatpak: use cached version for pygobject
There is no points relying on git master, just pick one version, this

Benjamin Tissoires d86d3ce4a7 setup.py: fix pyxdg requirement
xdg is declaring itself as pyxdg.

Detected when installing through flatpak. It tries installing 'xdg'
through pip while we already manually installed it:

Peter Hutterer b749cad77e setup.py: don't require 'gi'
Turns out this is not the gi.repository but a different package:
    'Command line to private gist.  Example: gi.py myFile'

It's incompatible with python3 and fails on import and seems to conflict with
gi.repository (also, the upstream seems dead).

Fixes #103

Peter Hutterer 7e751d45c8 base: if gi.repository fails to import, warn
We need python 3.6 but old Ubuntus only have 3.5. 3.6 can be installed (and
thus we get past the 3.6 sys.version check), but the gi.repository backports
are in various states of disarray (see #103 and #104).

And Python (and in particular gi) makes it hard for users to distinguish
between "the dependencies are a mess" and "this is a bug in tuhi".

So let's catch any error during gi.repository import and print a warning to
the user, in the hope of getting less bugs caused by Ubuntu frankenpythons.
Still won't fix issues like #104, but I'm not sure how to test for those
errors.

Related to #103

Peter Hutterer caf1264952 dbus: add file format version negotiation for the JSON data
Export the supported versions in a Manager property and require the client to
request a specific version in GetJSONData. Without that, the server could
never update the format and clients would have to support every single
historical version to make sure they can run against any version server.

Peter Hutterer d4ea6e3938 dbus: change the JSON timestamp argument to 64 bit
Because we're totally going to ship tuhi in embedded devices that are going to
be in use until after 2038 when time resets to zero, the world goes big bang
and the only survivers will be 64-bit species. Or something like that. Either
way, the API documentation already said so anyway and the DrawingsAvailable
property is already 64 bit too.

Semi-confusingly: the dbus 64 bit unsigned type is 't', it doesn't stand for
'timestamp'.

Benjamin Tissoires 789c098e82 wacom: do not timeout on long drawing retrievals
It can easily take more than 5 seconds when reading the data. The current
timeout just cuts the connection while it is still reading.

We *could* just remove the timeout here as the device will gracefully
send us a 0xc8 opcode with a blank CRC if we shut the device down while
retrieving the data.

However, better being on the safe side and keep a timeout, but restart it
if we are still getting pen data during the timeout.

Benjamin Tissoires a5cb084a31 wacom: use semaphore instead of polling
Using polling is bad, true, but it worked. However, using a Semaphore
is better and we can directly benefit from the internal timeout
implementation.

Benjamin Tissoires be2ac9fed3 wacom/live: take into account 'physical' borders of the bloc of paper
When using the live mode on the Slate, the bloc note actually hampers
the pen and prevents it to address all of the pixels on the screen.

Add some artificial boundaries that roughly match the primary design
of the device.

The Intuos Pro has a clip where you put a regular sheet of paper, so there
is no point restraining the active surface.

Peter Hutterer 5692a1f3b2 wacom: add PacketHandlers for handling special commands
For data packets other than basic motion/pressure strokes, add a PacketHandler
that can deal with that particular packet. Those handlers are part of the
class declaration, when we instantiate a protocol we pull them all into a
packet_handlers list and go through them. The first one to return True is
considered the right handler and we expect something has been done with the
packet.

This patch includes the handlers for the end-of-stroke and end-of-sequence
packets, the rest to be added later.

Peter Hutterer 23e18cea67 drawing: add a stroke.seal() functionality

Peter Hutterer 7796d3c110 wacom: don't add points to the log until we have an absolute value
On the Intuos Pro at least we sometimes get events that are all relative at
first and it can take several events for us to have all three values as
absolute. This is likely a parsing error on our side, but meanwhile don't
write the data until we have at least one known value for all three axes.

And because the SVG writer isn't happy with empty strokes, add a seal()
function to the drawing to purge empty strokes.

Fixed #92 or at least works around it

Peter Hutterer 8ecc397303 wacom: skip over the prefix when handling pen data
The prefix (4 bytes on the spark/slate) is some data that we don't know yet.
It *could* be the size of a tablet/drawing in LE byte order: 14434x29794
although that doesn't quite match the Intuos Pro data where the prefix is
different.

Either way, having this be an opcode of 0x3800 was probably just coincidence.
Let's skip over the header normally and assume that once we have a prefix, we
have a drawing. This opcode never occurs a second time within the same
drawing.

Peter Hutterer 876f35f806 wacom: factor out the prefix handling
The Intuos Pro has a different prefix, we'll need to override this. Dropping
the comment about the 8bt, on the intuos pro the prefix is nonsensical so
let's not leave a false lead there.

Peter Hutterer 726362107b wacom: append multiple nordic answers to each other
On the Spark, the 0xc9 CRC comes almost immediately after the 0xc8
end-of-sequence. This causes a race condition where sometimes we process the
0xc8 before the 0xc9 arrives, other times the 0xc9 overwrites the current
nordic_answer value before we get to it - triggering an unexpected opcode
exception.

Fix this by appending the nordic answer and only ever pulling off enough to
satisfy the current request.
