|
Overview
|
|
|
|
This extension allows the user to create a context with exact major and
|
|
minor versions. By default, a context may be created of any version that
|
|
is backwards-compatible with the requested verion but it is often useful to
|
|
users to request and target a specific version.

|
|
|
|
+ The context returned must be the specified version, or a later version
|
|
+ which is backwards compatible with that version if
|
|
+ EGL_CONTEXT_OPENGL_BACKWARDS_COMPATIBLE_ANGLE is EGL_TRUE.
|
|
|
|
Append to section 3.7.1.1 "OpenGL and OpenGL ES Context Versions":
