Module custom_shader_renderer 

Custom shader renderer for post-processing effects

Supports Ghostty/Shadertoy-style GLSL shaders with the following uniforms:

• iTime: Time in seconds (animated or fixed at 0.0)
• iResolution: Viewport resolution (width, height, 1.0)
• iChannel0-3: User texture channels (Shadertoy compatible)
• iChannel4: Terminal content texture
• iTimeKeyPress: Time when last key was pressed (same timebase as iTime)

Ghostty-compatible cursor uniforms (v1.2.0+):

• iCurrentCursor: Current cursor position (xy) and size (zw) in pixels
• iPreviousCursor: Previous cursor position and size
• iCurrentCursorColor: Current cursor RGBA color (with opacity baked in)
• iPreviousCursorColor: Previous cursor RGBA color
• iTimeCursorChange: Time when cursor last moved (same timebase as iTime)
