[C#] Notification bitmap stops displaying going from 32bit to 64bit openvr_api.dll

[BOLL7708]

This is using the C# headers.

For me running this test project loads a bitmap off of disk, prepares it and successfully displays it in the notification that pops up in the headset.

If the only change I do is switch to the 64bit .dll there is no error, but the bitmap is no longer displayed, it's just an empty space.

Am I missing something obvious I need to do here? 🤔 I have spent a bunch of hours trying to kick it into submission as 64bit with no success.

Since SteamVR Unity plugin is preferred at x64 most Unity Devs are hit by this problem, me included.

Thanks for reporting. I've got a fix coming for this.
