pixelmager

a tool like colorcop, but with the purpose of inspecting pixels, rather than picking colors.

• resizable window like gifcam
• zoomed window next to org pixels
• levels-filter
• run random shader on image
• before/after snapshots in tabs to flip between
• and diff-tool?

analysis

• live histogram / waveform?
