Is there something equal to GetItemIcon for spells?

[slizen]

Since you can get the icon of any item by using GetItemIcon() even if you haven't got it cached it would be kinda logical that there would be something similar for spells. I've been searching forever but I can't find any.
Now why would blizzard make us able to get all item icons but not all spell icons?

Edit: While I'm at it, is there any way to get the text a tooltip contains?

GetSpellInfo(spellId) returns the icon path

name, rank, icon, cost, isFunnel, powerType, castTime, minRange, maxRange
= GetSpellInfo(spellId or spellName or spellLink)

Ah yeah, but it only works with spellLink/spellName if you know the spell, and there is no way to find out spellID's for unknown spells ingame.
It's the same for items, except there is GetItemIcon() to get around this, I'm just wondering if there is a similar workaround for spells. Anything that isn't a database with for example spell names paired with their spellid's.

LibBabble-Spell-3.0, it has a few api documented here but better to read the code to have all of them, there is way more functions inside.
