CSS filter support in LESS

[alibby251]

Hi,
I've been playing around with the CSS filters that are supported in LESS, and happened to notice that not all appear to be included. Whilst I know that they could be added using normal CSS, do you have any plans to extend support to those filters you don't already include, such as hue-rotate or sepia?

Also, I noticed that neither blur nor brightness are listed as such - is this because LESS refers to them using different names, or are my eyes deceiving me? ;-) I'm using LESS 1.7.0 at the moment - I think 1.7.3 is out, and am happy to upgrade if any of the above is supported in that version.

Well, Less operates on colors not images so things like blur are simply impossible. Things like hue-rotate or sepia probably just having different names in context of color processing (i.e. spin and saturate + set hue). For the brightness (assuming HSV brightness) see #1853.

And finally any color filter can be implemented using available functions and/or arithmetic ops.
