drawBitmap2 and tintColor

Hi,

I'm experimenting with drawBitmap2. The bitmap and transform/filterMode work well but I'm having trouble using tintColor.

I have tried with the default launcher_icon.png and my own RGBA png image containing white, black and transparent parts.

I've used both hex color as well as the predefined Graphics colors, but the tint color seems to have no effect. What am I missing?

Cheers,

Pär
