[gschneider] 42291: user32: - Restructure and simplify CreateCursorFromData - Call CreateIconFromResourceEx properly allowing it to create colored icons (although it doesn't care about that yet) - Fix some comment typos win32k: - Don't just copy the pointer to an XLATEOBJ, copy instead. The caller will free it, EngSetPointerShape will do so too (causing either double-frees or memory write errors)

- Fix some comment typos
win32k:
- Don't just copy the pointer to an XLATEOBJ, copy instead. The caller will free it, EngSetPointerShape will do so too (causing either double-frees or memory write errors)
