Spacing around [h] figures in doublespaced documents

Hi,

I'm working on improving the thesis/dissertation template for my 
university. It's required to be doublespaced, which introduces excess 
space below [h] floats and the text. This can be fixed manually with a 
negative \vspace of course, but I would prefer to find an automatic 
solution. Are there any hooks for [h] floats alone, or will I have to 
somehow redefine the float environments? (I skimmed over ltfloat.dtx in 
source2e.pdf and that seems like a bad idea, given my current skill level)

Thank you,

Jordan Savoie
