    GL Extension XXX

Dependencies
30

31
    OpenGL ES 1.0 is required.
32

33
    EGL_ANGLE_explicit_context is required.

35
Overview
36

37
    This extension adds new OpenGL ES entry points that allow the user to pass the current EGL
38
    context as a function parameter. This allows users to skip lookup of the thread's current
39
    context upon entry.

New Types

45
New Procedures and Functions
46

47
    For every OpenGL ES entry point available in OpenGL ES 1.0, an additional entry point is made
48
    available. The entry points have the form of:
49

50
    <return value> gl<entry point name>ContextANGLE(GLeglContextANGLE context, <entry point parameters>)
51

52
    If a function already has an extension suffix, this form still applies.

Additions to Chapter 2 of the OpenGL ES 1.0 Specification (OpenGL ES Operation)
59

60
    The ContextANGLE entry points allow the user to pass the current EGL context as a function
61
    parameter to provide better performance than looking up the current EGL context at every GL
62
    entry point.
63

64
    Calls made with an explicit context provide no additional validation for the passed context
65
    parameter.
66

67
    Calls made with an explicit context will generate errors under the same conditions as they
68
    would without an explicit context. Any instances of undefined behaviour without specifying
69
    an explicit context are still undefined when specifying an explicit context.
70

71
    When an EGL context that is not current is explicitly passed, the resulting behavior is
72
    undefined.

    None.
