Cutting textures to objects shape

[piotr.w...@gmail.com]

Hi All, 

I am little lost now, I stuck on having textures rendered only to objects borders. For now I am rendering rectangles, but I expect in my engine also circles and triangles... 

I went though Image, Image Surface and ImageLayer, but I did not find anything about alpha channels or somehow blending. 

I have 1.8.5 PlayN version and I do not want to target for web-gl, just HTML and canvas. 

Thanks, 
Piotr

Should it by done by mixing two layers in group ? Like that below:

- layer with only alpha channel 

- layer with texture 

?
