DisplayInformation missing on Windows in 1.9.0

[Yaio]

This program:

import direct.directbase.DirectStart
di = base.pipe.getDisplayInformation()
num_dm = di.getTotalDisplayModes()
print num_dm
print [(di.getDisplayModeWidth(idx), di.getDisplayModeHeight(idx)) for idx in range(num_dm)]
run()

correctly prints:

188
[(640, 480), (640, 480), ... , (1440, 900)]

with Panda3D 1.8.1, but it prints:

0
[]

on the same computer with Panda3D 1.9.0 and the current devel from buildbot.

It happens on a computer with Windows 7 64 bit; GeForce GTX 980; driver version 353.30.

It's because the Config.prc variable "request-dxdisplay-information" is now set to false by default, because this querying mechanism made the start-up time very slow and consumed a lot of GPU resources. You can enable it if you want this information.

I found a Win32 API we can use to get this information anyway. I checked in support for that. So, in 1.9.1, you will be able to get display modes again, even with the default settings.
