maximizing browsers on multi-display setup is sizing wrongly

Testing with both 1.0 r14402 fedora 23 server against a 1.0 r14397 windows client and 0.17.1 r 12453 fedora 23 server against a 0.17.5 13487 windows client... with two displays, I'm finding that maximizing a browser window (chrome, firefox) causes it to size across both displays... but only if I maximize from the left-most display.

Fullscreen with videos behaves as expected.

I'll attach client-side logs for both combinations with -d window... looks like there's a init_max_window_size(..) max-window-size changed from (0, 0) to (4096, 4096), because of max viewport dims (8192, 8192) and max backing dims (4096, 4096) call being made in each case, with a desktop/display set up of:

 desktop size is 3840x1080 with 1 screen:
  Default (1016x285 mm - DPI: 96x96) workarea: 3840x1040
    DISPLAY1 1920x1080 at 1920x0 (621x341 mm - DPI: 78x80) workarea: 1920x1040
    DISPLAY2 1920x1080 (621x341 mm - DPI: 78x80) workarea: 1920x1040

• Another extremely interesting note... this only happens when both displays are very close to the same size (both 1920 x 1080; one 1920 x 1080 and the other 1920 x 1200; one 1920x1080 the other 1920x1440; 1920x1080 & 2048x1536... but as soon as I reach 1920x1080 & 2560x1440 the maximize begins to behave as expected.

Window positioning and maximization is fixed using the new dummy driver and configuring virtual monitors to match the client's geometry exactly: #56 (comment)
