- Fix a coordinate problem that occurred with alphablend in DrawIconEx (32bpp mode only)

Browse source 
- Welcome back mixer icon in 32bpp mode!
- Note for other invisible icons in that mode: 32bpp icon variants are most likely missing in the *.ico file; ReactOS image bpp conversion functions currently clear the alpha channel -> invisibility
- Update function names in debug prints, remove duplicate code, slightly improve code readability
