c15008e72e Move all debug flags in a single place. 
This change also adds a new memory usage flag. When turned on, the
following is printed after every frame:

D/OpenGLRenderer( 3723): Current memory usage / total memory usage (bytes):
D/OpenGLRenderer( 3723):   TextureCache          3766680 / 20971520
D/OpenGLRenderer( 3723):   LayerCache            3538944 /  8388608
D/OpenGLRenderer( 3723):   GradientCache          135168 /   524288
D/OpenGLRenderer( 3723):   PathCache               41180 /  4194304
D/OpenGLRenderer( 3723):   TextDropShadowCache         0 /  2097152
D/OpenGLRenderer( 3723):   FontRenderer 0         262144 /   262144
D/OpenGLRenderer( 3723):   FontRenderer 1         262144 /   262144
D/OpenGLRenderer( 3723):   FontRenderer 2         262144 /   262144
D/OpenGLRenderer( 3723): Other:
D/OpenGLRenderer( 3723):   FboCache                    2 /       12
D/OpenGLRenderer( 3723):   PatchCache                 31 /      512
D/OpenGLRenderer( 3723): Total memory usage:
D/OpenGLRenderer( 3723):   8268404 bytes, 7.89 MB

This should help tracking possibe memory issues.

5b3b35296e Optimize FBO drawing with regions. 
This optimization is currently disabled until Launcher is
modified to take advantage of it. The optimization can be
enabled by turning on RENDER_LAYERS_AS_REGIONS in the
OpenGLRenderer.h file.
