I believe regular Ctrl does not have this issue.

When one sets alpha of upper Image to 0 or 255 it works as expected.
But when eg 10,100, etc is used - blending is kinda weird hybrid.
Lowest fn that is executed is: void GLDraw::PutImage(Point p, const Image& img, const Rect& src).
I tried different settings, like ...GL_ONE,GL_DST_ALPHA... - but no go.
