"Open resource..." window now takes twice as long to open

[irock]

The "Open resource..." window is noticeably slower to open now.

Stopwatch benchmarks from my project:
b10658: roughly 0.5 seconds
b10799: roughly 1 second

Is this because the list now displays behavior icons? It used to display a green puzzle piece for all of them.

For what it's worth, the default hammer behavior icon isn't really readable at this size.
