Currently the alpha channel is completely ignored by basebmp. However this results in completely "transparent" output, meaning the client has to manually overwrite the alpha channel -- instead we now set it automatically when writing colourdata. Unfortunately this doesn't quite work -- it seems that drawing a non-opaque bitmap/image on top of the existing bitmap can erase the alpha channel information (i.e. these areas will once again be transparent -- for example document borders seem to have a transition effect overlayed onto them): presumably there is some method that bypasses our RGBMaskSetter (probably some form of direct manipulation of raw values?). manipulation in basebmp Change-Id: Ia4be6a748cc30191a4422121f9ec347d9198b225
