+Subject: [PATCH] egl: use device dispatch if at least one vendor suceeds
+
+Currently, in InitDeviceListInternal if any egl vendor fails to list
+its devices for any reason the construction of the device list is
+abandoned. That means that even if we have one vendor successfully
+serving the application, the failure of another vendor library will
+break any api calls related to egl devices.
+
+Instead, if a vendor fails queryDevicesEXT the device mapping logic
+should proceed as if it listed no devices. If the relevant device
+belongs to the failed vendor then the dispatch will still fail with
+EGL_BAD_DEVICE.
