- Adds ImageCanvas — a VisPy 2D image viewer with pan/zoom, ROI selection, line ROI, pixel hover stats, FPS overlay, and live binning (none/stride/mean)
- Adds Histogram widget with optional log/sqrt/linear scale, colorbar strip, draggable level handles, and auto-scaling
- Adds dark/light background support, theme-aware hover colors, and live theme switching
- Adds render_to_array for framebuffer readback on both ImageCanvas and LinePlot
- Adds display norm (linear/sqrt/log) to both histogram and image canvas
- Adds pyopegl dependency for OpenGL acceleration
