1c740bce8a Document the implementation of saveLayer(). 
The implementation is simple but tricky. Leave explanations to my
future self so that I don't invent a time machine to come back to
now and slap my self.

This change also simplifies the way the GL blending function is
chosen when compositing a layer. It reuses existing OpenGLRenderer
APIs and is easier to understand.

d90f23e24a Do not convert 8888 bitmaps to 565 when doing a copy. 
Bug #2988077
This change keeps the 8888 format for new bitmaps and also keeps,
when possible, the opaque flag.

1639351139 Make libhwui entirely optional. 
The makefile variable USE_OPENGL_RENDERER must be set to true to compile
libhwui and the related code in the JNI layer.

This change also removes obsolete APIs from Canvas that must not be used
and would be confusing if left in. These APIs were remnants of our first
attempt at an OpenGL renderer for the view hierarchy and had not been
taken out before Android 1.0 was released.

9cccc2b9bd Enforce maximum texture size. 
When an app tries to render a bitmap or path larger than the GPU's maximum
texture size, the drawing command is ignored and a warning is logged. This
change also makes texture drawing more robust by catching potential errors
during texture creation.

This change also fixes a crash in the FontRenderer. The destructor would
sometimes try to free an uninitialized array.
