Description
Graphics.pas maintains a private list of registered TGraphic derived classes
that are currently in use on a given running application and at design-time under the IDE (for example you can have installed or used TJPEGImage, TPNGImage, TGIFImage, etc, etc).

The wish is to have access to the list of classes, or to the private "FileFormats" variable in Graphics.pas, or some public method that can enumerate those classes.

One example of use would be showing a dialog to export a picture to any of the registered graphic formats, without having to explicitely to declare which formats or use the units that register them.

This would be very useful. Up till now I've been modifying Graphics.pas and moving things around to make it work how I like. :P Which, BTW, is also a good workaround if you're not using packages.

BTW: This is the second dupe of an earlier report:

There is also a (more comprehensive) duplicate of this report: QC 57402. Voting here as there are more votes existing.

It would be great if you Codegear/Embarcadero guys could invest some minutes on this issue.
