Hello, thanks for making this plugin. I created a similar one but I toggle it on and off with a command. Wouldn't it be much better from a performance point of view to use toggling instead of CursorMoved, CusorModedI ? Maybe some feature options like g:css_enable_toggle = 1. I read someone with a similar issue #126 . When you toggle on, create the groups. When you toggle off delete them. What do you think ?

for color in css_colors
syn clear color
endfor

I'm pretty sure, this has something to do with my configuration because I tried with another user account and I don't have that problem. When I comment line 242 in css_color.vim it works fine:

autocmd ColorScheme <buffer> call css_color#reinit()

Any pointers would be appreciated thanks.
