app_server remote/html5 won't work correctly on x86_64

[xyzzy]

The remote and HTML5 drawing engines in app_server currently use (uint32)this as some sort of token: ​http://cgit.haiku-os.org/haiku/tree/src/servers/app/drawing/remote/RemoteDrawingEngine.cpp#n25 and ​http://cgit.haiku-os.org/haiku/tree/src/servers/app/drawing/html5/HTML5DrawingEngine.cpp#n26

There are already comments saying that they need fixing for 64-bit. I don't have enough knowledge of how the code works to be able to fix it, so for now I'm just not going to compile in those backends on x86_64.

This seems like the same sort of thing as the cookies in the input_server we have been discussing in the other ticket, so I don't think a pointer is really required either.

It seems like the server side could be changed and the RemoteDesktop client application would not need to be changed. But I'm just not sure how unique the tokens need to be and if they need to be unique between different Haiku machines (in other words, is something smarter that token++ needed.)

Some time ago I tested the remote app server and the concept of the HTML5 drawing engine is intriguing, so after the alpha 4 release I may try to get a testing environment set up for these and could see if changing to a more simple int ID format is possible.

RemoteDrawingEngine was fixed at some point, and HTML5DrawingEngine has now been removed. Closing.
