Fixed an issue with the glBlendingMode that was causing the result to be pre-multiplied twice.
Fixed an issue that was causing images that have a data window that is wider than the display window but with matching heights to be entirely rendered when areas outside of the display window should be greyed out.
Changed the minimum filter to GL_LINEAR for the image viewer.
Moved the glBlendFunc into the renderImage method.
Refactoring GraphGadget::connectionGadgetAt
The public and private functions are now completely separate, reducing unneeded calls to GraphGadget::nodeGadgetAt and Gadget::select during drag-reconnect queries.
Removed the texture filter arg from StandardStyle::RenderImage().
Added the texture filtering to a scope within ImageView::doRender.

It's going to get a bit more complicated with the in-stream insertion code, so I'm simplifying it a bit beforehand.
