#1972 closed enhancement (done)
The TypeSelector dialog takes too long to show

Description
When creating a new user-defined algorithm and adding a LookupParameter<T>, the time to wait until one can select a certain type for T is too long. I measured the "Select Type of Generic Type Parameter" dialog to appear after 30 seconds on my notebook. The second time is faster (3 seconds), I grant, but if you open the dialog for creating parameters in a different view, it takes 30 seconds again. While waiting HL appears frozen as the operation blocks the UI thread.

Two ideas from our discussions:
- types can be discovered (asynchronously?) at start-up and then be cached by the plug-in infrastructure
- only assemblies belonging to plug-ins should be searched for HL types (currently, all types in all loaded assemblies are searched, including framework-assemblies)

The profiler showed that interestingly the problem is not type discovery but the ImageList used in the TypeSelector!

r10497: workaround to improve performance of type selector (the problem is that imagelist methods are SLOW)

After r10497 "Select Type of Generic Type Parameter" dialog takes around 1sec to appear on my workstation.

I also attached a patch for the plugin infrastructure to cache assemblies for type discovery. However, after the simple change in the TypeSelector (r10497) the effect of further changes in the plugin infrastructure is negligible.

This is much faster now, great!
