New Item templates for editor extensions for Visual Studio 2010.
A template for adding a command filter to IVsTextView instances. A command
filter is a component that gets an opportunity to observe and handle commands
before and after the editor acts on them.
A very simple skeleton for a tagger provider and tagger. The template uses
a SimpleTagger<T> by default for the actual ITagger<T> implementation,
with TODOs about replacing it with a more fitting data structure.
A more complex skeleton for a tagger provider and tagger that updates its
collection of tags on a background thread, in response to edits on the buffer.
By default, this stores tags in a SortedList, which can/should be replaced
with a structure that more naturally aligns with the type of data the tagger
is updating. This also includes decently accurate code for keeping a
SortedList<ITrackingSpan, T>, and code for simultaneously iterating a
NormalizedSnapshotSpanCollection and a sorted collection of tracking
spans (in the implementation of GetTags).
