Class to aid in the rendering of RawData objects.
This class prepares the rendering of the raw digits content for the 2D view of the display. In particular, it fills the 2D view of detected charge vs. time and wire number for a single TPC. The code is not ready to support an arbitrary TPC from the detector; it can be fixed to support that, but a good deal of the calling code also has to change.
As of August 2015, this class performs some preprocessing for the data to be displayed. The main argument here is that the display assigns to each plane a space of 600x250 pixels, while the amound of data is typically 500x5000 elements. These numbers vary wildly: while the first number is close to the current default size for a new window, that window can be resized and windows many times larger can be obtained; for the data content, a MicroBooNE plane contains 2400x9600 elements (that's roughly 25 millions, and there is three of them), each of the two LArIAT planes contains 240x3200 (less than 1 million), and a single TPC of DUNE's 35t prototype about 350x4800 (but it is larger when extended readout window modes are used). The code produces TBox'es to be rendered by the nuevdb event display infrastructure. The code before August 2015 would produce one box for each of the aggregated charge; charge could be aggregated in time by FHiCL configuration to merge TDC ticks. This typically bloats rendering time, since rendering of all boxes is attempted. The new code performs dynamic aggregation after discovering the actual size of the graphical viewport, and it submits at most one TBox per pixel. Additional improvement is caching of the uncompressed raw data, so that following zooming is faster, and especially a way to bypass the decompression when the original data is not compressed in the first place, that saves a bit of time and quite some memory.
