+
+
+ @SYMTestActions
+ Acquire the glyph cache's usage and other metrics.
+
+ Populate the glyph-cache.

+ Acquire the glyph-cache's usage and other metrics.
+
+ Precipitate an Out-of-Graphics-Memory condition, triggering the GOOM monitor.
+
+ Acquire the glyph cache's usage and other metrics.
+
+ Ensure the glyph-cache has been cleared and its maximum limit reduced.
+
+ Precipitate a MemoryGood() call from the GOoM framework.

+
+ @SYMTestExpectedResults
+ The glyph-cache should be cleared in response to OoGM condition and its upper limit reduced.
+
+ The Glyph-cache's upper limit should be reinstated in response to a memory-good notification.
