gegl r2952 - in trunk: . tests

Log:
Add a simple tests case to ensure processing and caching sanity

Add a simple tests case to ensure processing and caching sanity. The
test case constructs a simple graph, processes it, checks the result,
changes input, processes again and finally checks the result a second
time. This test will immediately catch severe regressions.
