22 * Contains class for icon generation in the backend
23 * This library has functions that returns - and if necessary creates - the icon for an element in TYPO3
25 * Expects global vars:
28 * - $TCA, $PAGES_TYPES
32 * These functions are strongly related to the interface of TYPO3.
33 * Static class, functions called without making a class instance.

473 * The only drawback is (apparently) that IM creates true-color png's. The transparency of these will not be shown by MSIE on windows at this time (although it's straight 0%/100% transparency!) and the file size may be larger.
