32
    OpenGL ES 2.0 is required.

Overview
35

36
    Adds a query for a serialized string representation of a context.
37
    Useful for testing to easily compare two states.

Additions to Chapter 6 of the OpenGL ES 2.0 Specification (Querying GL State)
46

47
    Update Section 6.1.5 "String Queries" to accept the new enum specified
48
    above. The SERIALIZED_CONTEXT_STRING_ANGLE string is an implementation-
49
    dependent representation of the current context state. Two contexts
50
    with the same internal state are guaranteed to have the same value. Note
51
    that the reverse is not true - two contexts with different states are
52
    may also have the same serialized string.

New State
55

56
    None.

Issues
59

60
    1) Should two contexts with different states return different strings?
61

62
    RESOLVED: We don't provide a guarantee that every state is serialized
63
      into the string. This loose wording lets the extension provide
64
      some additional extra validation without being overly strict and
65
      making the implementation difficult. It also allow a no-op
66
      implementation to satisfy the extension requirements.
