clear-screen

Documentation

Overview

Simplest GLES2 example: clear the framebuffer to a known color and verify.

Demonstrates:

• EGL offscreen context setup (pbuffer surface)
• Setting the clear color with ClearColor
• Clearing the color buffer with Clear
• Reading back pixels with ReadPixels to confirm the result

This is the "hello world" of OpenGL ES -- no shaders, no geometry, just proving that the GPU pipeline is alive by writing and reading a pixel.
