wineps.drv: Return correct values for DESKTOPHORZ/VERTRES since they are used to setup the visible region.

(spotted by Alessandro Pignotti).

winex11.drv: Do not ignore the keysyms assigned to a group switch, it leads to side effects like missing KeyRelease events.

Only objects that have been registered for a class context that matches 
the requested class context should be returned.

ole32: OleLoad should call CoCreateInstance with CLSCTX_INPROC_SERVER as well as CLSCTX_INPROC_HANDLER.

This ensures that applications that change the strings received in
status callbacks don't affect the data needed to successfully connect to
the correct server.

Add a test to show that PackageCode is set by MSI.

Create an array of handles to wait on so that we can wait without
holding a critical section.

Add tests for these properties.
Update the todo list of properties to set.

When drawing processed vertices with the fixed function pipeline the
projection matrix is set up to map y values from 0 to height to 1.0;
-1.0(gl and d3d coord systems are flipped). This moves the y axis to
the bottom of the drawing area. When later on the y inversion matrix
is applied for offscreen rendering, the coordinate system will get
flipped out of the viewport.

This patch sets the Y range up upside down when using offscreen
rendering, so the invymat will flip it to the correct position. This
has to happen before the 0.375 pixel correction.
