This function displays source control properties for a file or project.
The source control plug-in implementation of this function is expected to return one of the following values:
Properties were successfully displayed.
The version control system has modified the file properties, so the IDE should reload this file.
The specified project has not been opened in source control.
The user is not authorized to view properties of this file or project.
The specified file or project is not under source control.
An unknown or general error occurred.
The source control plug-in displays the properties in its own dialog box.
The properties are defined by the source control plug-in and may differ from plug-in to plug-in. If the plug-in allows the user to change the source control properties of a file, it should return SCC_I_RELOAD to signal the IDE that this file or project needs to be reloaded.
