Open-source toolset for spherical imaging.

• lower requirements to OpenGL 2.1 and GLSL 120
• log OpenGL and GLSL version info for the acquired context

• add zoom
• fix horizontal alignment of checkboxes on the Layer UI

• add Layer memory usage indicator
• allow invocation without inputs

• switch to PySide for graphical UI
• layers, layer list view
• per-layer controls: visibility, alpha, moving, orientation, file name
• layer list controls: drag and drop, add (open file) & remove layers

• support for multiple image formats via Pillow
• auto-detect projection based on aspect ratio
• convert between projections
• conversion code complexity is O(n) instead of O(n^2) in number of projections
• supported projections: Equirect, CubeMap

• simple command-line and graphical UI using Pyglet and OpenGL
• quaternion based orientation
• GLSL based back-projection

• simple command-line UI
• switches for overriding input and output projections
