[urgent] _hideShowColumn() 's setSize()

Hi, ^^;;

I want to hidden many columns at once.

So, I call setColumnHidden(), but, it’s too slow because of many setSize()'s call.

So, I update _hideShowColumn() in dhtmlxgrid.js to work setSize() after calling all setColumnHidden().

But, the resizing doesn’t work well. so, data on cells becames wrong.

Help me plz…-T_T-

Please contact support@dhtmlx.com and provide your updated _hideShowColumn() function.
