--Conditional assignment: collect all renderer classes that match
--the name pattern "Quicksilver*" and if exactly one was collected,
--assign an instance of it to the current renderer:
theRenderer = for i in RendererClass.classes where \
matchPattern (i as string) pattern:"Quicksilver*"collecti
#(Quicksilver_Hardware_Renderer)
if theRenderer.count == 1 do renderers.current = theRenderer[1]()
Quicksilver_Hardware_Renderer:Quicksilver_Hardware_Renderer
--Using the class as string to pattern match the name is
--useful when the actual class name is changing (for example
--some 3rd party renderers include the version number in the
--class name, making it difficult to hard-code in scripts for
--more than one version).
--The above approach would work with these cases, too.
