Changing color in transparent PNG

[David O'Neil]

Create a rectangle with a fill that you want, then use the bitmap for its transparency, then clone until the colors are vivid enough for you.

Doing it in scratch in X4 (X5 too?) reveals a real annoyance with Xtreme. When the transparency is applied to the rectangle, it won't keep its original aspect ratio. Maybe there's something I'm overlooking?
