  Status
  
      Draft
  
  Version
  
      Last Modified Date: April 20, 2023
      Revision: 1
  
  Number
  
      OpenGL ES Extension XX
  
  Dependencies
  
      None
  
  Overview
  
      This extension allows skipping texture format renderability validation if
      the implementation is capable of rendering to the underlying texture
      format. This can be useful in situations where textures are created
      externally and the current context's version and extensions do not allow
      rendering to the texture but the implementation is capable.
  
  New Procedures and Functions
  
      None
  
  New Tokens
  
      Accepted as a value for <pname> for the TexParameter{if} and
      TexParameter{if}v commands and for the <value> parameter of
      GetTexParameter{if}v:
  
          GL_RENDERABILITY_VALIDATION_ANGLE     0x9EA0
  
  Additions to the OpenGL Specification
  
      None.
  
  New Behavior
      Additions to Chapter 3 of the OpenGL ES 2.0 Specification (Rasterization)
  
      Add a new row to Table 3.10 (Texture parameters and their values):
  
      Name                           | Type | Legal Values
      ------------------------------------------------------------
      RENDERABILITY_VALIDATION_ANGLE | bool | TRUE, FALSE
  
      Add a new section 3.7.x (Texture Usage) before section 3.7.12 and
      renumber the subsequent sections:
  
      "3.7.x Texture Usage
  
      Texture renderability validation can be controled via the
      RENDERABILITY_VALIDATION_ANGLE value for the <pname> argument to
      TexParameter{if}[v].
  
      Possible values for <params> when <pname> is TEXTURE_USAGE_ANGLE are:
  
      TRUE - the default. Renderability validation is unchanged.
  
      FALSE - Renderability of the texture becomes implementation dependent.
          The implementation will allow rendering to the format if it is
          capable."
