Ticket #410 (closed defect: fixed)

When using the -fast flag with the showinf command line utility, 16-bit and 32-bit data gets somewhat mangled. For example:

showinf -fast 'u32&pixelType=uint32.fake'

Rather than being scaled, the data is narrowed directly into an 8-bit range of values. Another example:

showinf -fast 's32&pixelType=int32.fake'

These problems are most likely a result of how the ImageTools.make24Bits methods behave. To fix, we need to decide how to scale higher-bit data down to 8 bits. The two easiest options are:

1. Scale linearly along the entire range of the larger bit depth. For example, with uint16 data, scale from 0-65535 to 0-255. The downside of this approach is that most 16-bit data will appear essentially black, as 16-bit data values often do not exceed 4096 in microscopy. The advantage is that this scaling method is what the default 16-bit color model uses when painting anyway, so the image should appear the same as without the -fast flag.
2. Scale linearly along the actual min and max of the image. This approach would use a MinMaxCalculator across the entire series.
