This has been a nuisance for us too --- we use gil to represent data from a telescope, where the scaling is a real pain as the floating point numbers represent the data read from the detectors.  It'd be nice if gil came with the needed typedefs for pure floating (32 and 64 bit) images/views (as well as the ones that scale in [0,1] which are presumably what others want).  It's too late to call the unscaled types 32f, but isn't 32F still available?
