Overview

This extension exposes the QCOM_render_shared_exponent functionality to WebGL.

The following WebGL-specific behavioral changes apply:

• Clearing or drawing to a shared exponent color buffer will generate INVALID_OPERATION if the associated color write mask has different values for red, green, and blue channels.

Consult the above extension for documentation, issues and new functions and enumerants.

When this extension is enabled:

• The RGB9_E5 floating-point internal format becomes color-renderable.
