Creates a new attachment for the input character ID which will be displayed until
vngen_attach_destroy is run. Multiple attachments can exist simultaneously, however no two attachments may share the same ID on the same character. VNgen entity IDs are arbitrary and most can be either numbers or strings, but bear in mind that -1 is reserved as 'null' and cannot be used as an ID. Unlike other entities, because attachments are specific to each character, attachments on other characters can use the same ID without conflict.
Note that all coordinates are relative to the parent character, including the z-index. For attachments, negative z-index will display the attachment in front of the parent character, while positive z-index will display the attachment behind them.
