UnifiedPDFPlugin::isFull[Main]FramePlugin() can have non-trivial overhead
when we do lots of coordinate conversions

Reviewed by Wenson Hsieh.
In some recent profiling, we have observed that isFull[Main]FramePlugin()
executions aggregate to a non-trivial execution time for flows that
require lots of coordinate conversions, such as find-in-page on a large
document. This patch tries to shave off some of that cost by caching the
results in question.
