[TYPO3-core] RFC #14324: Feature: Add spriteGeneratorAPI to support the new sprite-icon-api

[Steffen Kamper]

Hi Steffen,

i took a first look to the patch and here are some remarks, could you 
update the patch to these comments?

* please use CGL (missing spaces (function params, t3lib_spriteManager), 
"AS", closing strings with wrong indentation, missing phpDocs for class 
vars, missing phpDocs for functions (eg __constructor)

* we always use lower case filenames (class.t3lib_spriteManager.php)

* in t3lib_spriteManager line 119 - $cacheFile was never defined

I will do a deeper review soon.

vg Steffen
