Bug ID: 48364
           Summary: Clifford Thinking Adventures fails to start in some
                    configurations
           Product: Wine
           Version: 5.0-rc2
          Hardware: x86
                OS: Linux

gdi32: Return the current display frequency from GetDeviceCaps(VREFRESH).

It spews out a message box saying: "This program cannot be run with your
current monitor settings. Please reset your monitor to a minimum of 256 colors
before running Clifford."

In fact an 8-bit display device isn't necessary. What is necessary is for
EnumDisplaySettings() to return at least one device with a refresh rate equal
to the number returned by GetDeviceCaps(VREFRESH). Under normal circumstances
the latter returns 1, but the former may return e.g. 60.

The attached patch fixes this, and makes the game completely playable for me.
