How do i properly access images provided by the EXT_shader_image_load_store (https://www.khronos.org/opengl/wiki/Image_Load_Store) extension? it says on the site they use signed integer coordinates, but what space are these coordinates in? is the origin in the top left or lower left corner or in the center?

Although the index vector is signed, only non-negative values are valid. The origin is the same corner as for texture coordinates.
