I have a signal which is sampled at F1 hertz which I want to resample
at F2 hertz.  Neither F1 nor F2 divide each other evenly.  Are there
any methods which can be used to resample F1 directly (e.g. not first
transform it into some other domain)?

The only reference to resampling I can find in my DSP book involves
taking a DFT of the input signal, truncating or padding it as appropriate,
and then taking it's inverse.
