/**
 * Native bindings to the KHR_robustness extension.
 * 
 * 
Several recent trends in how OpenGL ES integrates into modern computer systems have created new requirements for robustness and security for GL
 * rendering contexts.
 * 
 * 
Additionally GPU architectures now support hardware fault detection; for example, video memory supporting ECC (error correcting codes) and error
 * detection. GL contexts should be capable of recovering from hardware faults such as uncorrectable memory errors. Along with recovery from such hardware
 * faults, the recovery mechanism can also allow recovery from video memory access exceptions and system software failures. System software failures can
 * be due to device changes or driver failures.
 * 
 * 
GL queries that return (write) some number of bytes to a buffer indicated by a pointer parameter introduce risk of buffer overflows that might be
 * exploitable by malware. To address this, queries with return value sizes that are not expressed directly by the parameters to the query itself are
 * given additional API functions with an additional parameter that specifies the number of bytes in the buffer and never writing bytes beyond that limit.
 * This is particularly useful for multi-threaded usage of GL contexts in a "share group" where one context can change objects in ways that can cause
 * buffer overflows for another context's GL queries.
 * 
 * 
The original ARB_vertex_buffer_object extension includes an issue that explicitly states program termination is allowed when out-of-bounds vertex
 * buffer object fetches occur. Modern graphics hardware is capable of well-defined behavior in the case of out-of- bounds vertex buffer object fetches.
 * Older hardware may require extra checks to enforce well-defined (and termination free) behavior, but this expense is warranted when processing
 * potentially untrusted content.
 * 
 * 
The intent of this extension is to address some specific robustness goals:
 * 
 * 

 * 
For all existing GL queries, provide additional "safe" APIs that limit data written to user pointers to a buffer size in bytes that is an explicit
 * additional parameter of the query.
 * 
Provide a mechanism for a GL application to learn about graphics resets that affect the context. When a graphics reset occurs, the GL context
 * becomes unusable and the application must create a new context to continue operation. Detecting a graphics reset happens through an inexpensive query.
 * 
Define behavior of OpenGL calls made after a graphics reset.
 * 
Provide an enable to guarantee that out-of-bounds buffer object accesses by the GPU will have deterministic behavior and preclude application
 * instability or termination due to an incorrect buffer access. Such accesses include vertex buffer fetches of attributes and indices, and indexed
 * reads of uniforms or parameters from buffers.
 * 
 * 
 * 
Requires {@link GL32 OpenGL 3.2}.

     * 
{@link GL11#GL_NO_ERROR NO_ERROR} indicates that the GL context has not been in a reset state since the last call.
     * 
{@link GL45#GL_GUILTY_CONTEXT_RESET GUILTY_CONTEXT_RESET} indicates that a reset has been detected that is attributable to the current GL context.
     * 
{@link GL45#GL_INNOCENT_CONTEXT_RESET INNOCENT_CONTEXT_RESET} indicates a reset has been detected that is not attributable to the current GL context.
     * 
{@link GL45#GL_UNKNOWN_CONTEXT_RESET UNKNOWN_CONTEXT_RESET} indicates a detected graphics reset whose cause is unknown.
     * 
     * 
     * 
If a reset status other than NO_ERROR is returned and subsequent calls return NO_ERROR, the context reset was encountered and completed. If a reset
     * status is repeatedly returned, the context may be in the process of resetting.
     * 
     * 
Reset notification behavior is determined at context creation time, and may be queried by calling GetIntegerv with the symbolic constant
     * {@link GL45#GL_RESET_NOTIFICATION_STRATEGY RESET_NOTIFICATION_STRATEGY}.
     * 
     * 
If the reset notification behavior is {@link GL45#GL_NO_RESET_NOTIFICATION NO_RESET_NOTIFICATION}, then the implementation will never deliver notification of reset events, and
     * GetGraphicsResetStatus will always return NO_ERROR.
     * 
     * 
If the behavior is {@link GL45#GL_LOSE_CONTEXT_ON_RESET LOSE_CONTEXT_ON_RESET}, a graphics reset will result in a lost context and require creating a new context as described
     * above. In this case GetGraphicsResetStatus will return an appropriate value from those described above.
     * 
     * 
If a graphics reset notification occurs in a context, a notification must also occur in all other contexts which share objects with that context.
     * 
     * 
After a graphics reset has occurred on a context, subsequent GL commands on that context (or any context which shares with that context) will generate a
     * {@link GL45#GL_CONTEXT_LOST CONTEXT_LOST} error. Such commands will not have side effects (in particular, they will not modify memory passed by pointer for query results,
     * and may not block indefinitely or cause termination of the application. Exceptions to this behavior include:
     * 
     * 

     * 
{@link GL11#glGetError GetError} and GetGraphicsResetStatus behave normally following a graphics reset, so that the application can determine a reset has
     * occurred, and when it is safe to destroy and recreate the context.
     * 
Any commands which might cause a polling application to block indefinitely will generate a CONTEXT_LOST error, but will also return a value
     * indicating completion to the application.
