If there're overviews, just use them for rendering
...
The current code falls back to the base table for small scales.
That approach has some drawbacks cause it forces the original table to
share some conditions with its overviews (same SRID, alginment, scale
constraints) for the rendering to work properly.
What we propose is to always fall back to the highest resolution
overview (lowest scale), rather than the original table, in order to
avoid coupling the original table with the constraints imposed by
rendering and still have them linked (in postgis raster metadata).
Please note this approach is not 100% compatible as the base table
won't be used. This should be no big deal because overviews can have
an arbitrary resolution/scale.

Move image_data.hpp to image.hpp and renamed most everything from image_data to image alone. This might lead to the need to clean up some variables that are currently named image through out the code at some time, but I think in the long term is much better as image is a better name for the base class.

Moved premultiply and demultiply out of image_32 and other parts of the code. The image_data object is now responsible for keeping track of its own premultiplied_alpha status. Created a new utility method in image_util to preform premultiplication.

Added visitor pattern to several different methods as well to prepare for image_data_any including compositing.

Ignore overviews with 0 scale in pgraster
...
refs #2551
Postgis raster_columns view is returning NULL values for raster
overviews with large scale factors. That issue in postgis is described
in http://trac.osgeo.org/postgis/ticket/3006
This causes two main problems:
- The first overview with scale = NULL is wrongly chosen for rendering
always
- The messed up scaling factor causes the render symbolizer to spent
an insane amount of CPU and memory to render a messed up tiles.
The patch in postgis is expected to be released with the new version, a
few months from now.

make concrete image_data type names more expressive and explicit about color channels/depth:
...
image_data_32 -> image_data_rgba8
image_data_8 -> image_data_gray8
image_data_16 -> image_data_gray16
image_data_float32 -> image_data_gray32f
NOTE: currently image_data_gray16::pixel_type = std::int16_t (signed 16 bit int) to match GDAL
should we support unsigned types?
