Dan Stoza cb1fcdedaa libgui: Split SurfaceTexture tests into more files
Extract the many different test fixtures and suites in SurfaceTexture_test.cpp
into separate files. No real functional changes, just tweaking headers to keep
things building (and adding a few copyright headers I forgot last time).
