The "controls" div holds map controls suchs as the Zoom button and
it's separated from the map in order to have the controls on the top
of the page all the time.
The "document-container" div is the actual display of the document, is
what the user sees and it should be no larger than the screen size.
The "map" div is the actual document and it has the document's size
and width, this being inside the smaller "document-container" will
cause the content to overflow, creating scrollbars
Set the SLEEPFORDEBUGGER environment variable to the number of seconds a child
process should sleep before calling lok_init(), so that you have time to
attach the process in a debugger.
Add a new program, loadtest, that runs a requested number of client sessions
in parallel to a loolwsd server. A client session loads one of a list of test
documents, and does some operations on it.
Move the getTokenInteger() and getTokenString() functions out from LOOLSession
into a new namespace LOOLProtocol, as they are neeeded also in the loadtest
program.
Add, also in LOOLProtocol, functions to parse some of the messages from the
server. (In general that is done in client JavaScript code, of course; only
for testing purposes needed in C++ code.)
Updated the removeTile method to just mark the tile as
not current and the set _update method not to 'hide'
(set opacity to 0) tiles from the current zoom level
The document can be zoomed in an out. Each zoom level corresponds
to a 20% increase or decrease in tile dimmension (in twips).
Zooming doesn't work well yet. Tiles are removed and readded to
many times and it looks bad. Also the zooming center has to be fixed.
Handle the start of a child process when needed centrally, not in each command
handler.
Also, handle unrecognized commands always already in the parent
process. (Command syntax checks still done in child process, though.)
Tiles are now correctly displayed.
Layers that request tiles from a socket connection need to specify
the 'useSocket: true' option. This way layers that do not require an
internet connection can be added (like a grid, ruler, etc.).
I've also fixed some coding style problems suggested by lintjs
