Fix the alpha value in the default texture data

Browse Source 
When a layer is added to a pipeline without setting a texture it ends
up sampling from a default 1x1 texture which is meant to be solid
white. However for some reason we were creating the texture with 0
opacity which is effectively an invalid premultiplied colour. This
would make the blending behave oddly if it was used.
