// If we are showing a NOS that comes from a file, don't show the grid.
// Old Glue used to show the grid, but this introduces problems:
// 1. This means that the variable showing code has to look at the file to
// get current values, rather than just at the ATI. This means we need new
// functionality in the plugin class for pulling values from files.
// 2. The plugin class has to do some kind of intelligent caching to prevent
// hitting the disk for every property (which would be slow).
// 3. The plugin will also have to respond to file changes and refresh the grid.
// 4. This may confuse users who are expecting the changes in Glue to modify the original
// file, instead of them understanding that Glue overrides the file.
// I think I'm going to keep it simple and only show the grid if it doesn't come from file:
// Update Jan 24, 2019
// I thought about this problem for a bit and realized that this can be solved in two steps.
// 1. The problem is that if we show the values that come from the AssetTypeInfo on a from-file
// object, the default values in the ATI may not match the values of the object in the file, which
// has mislead developers in the past. That is why I opted to just not show a property grid at all.
// However, if we just didn't show any defaults at all, that would solve the problem! To do this, we
// just need to take the AssetTypeInfo, clone it, and make the default values for all variables be null.
// This should result in a property grid that shows the variables with blank boxes/UI so that the user can
// fill it in.
// 2. Plugins could be given the copied ATI to fill in with values from-file. If plugins don't, then the values
// would be blank, but if the plugin does want to, then the values from-file would show up.
// I'm not going to implement this solution just yet, but I thought of how it could be done and thought it would
// be good to document it here for future reference.
