In #7511 a global was added to allow the mouse speed to be adjusted on the client. This needs to be improved as there is one speed modifier.

• We currently use a int32_t as input for the modifier, perhaps it should be a double ?
• Change the setting to be Per-Client. Every client should have the ability to set a unique modifier if needed.
• Store the settings in the screens configuration within the server.
• Consider Adding additional scroll Speed modifier
