76 * Trace file version number.
78 * We keep backwards compatability reading old traces, i.e., it should always be
79 * possible to parse and retrace old trace files.
81 * So the trace version number refers not only to changes in the binary format
82 * representation, but also semantic changes in the way certain functions
85 * Writing/editing old traces will not be supported however. An older version
86 * of apitrace should be used in such circunstances.
91 * - initial implementation
94 * - support for GL user arrays -- a blob is provided whenever an user memory
95 * is referred (whereas before calls that operate wit user memory instead of
96 * VBOs should be ignore)
99 * - malloc/free memory calls -- allow to pass user memory as malloc memory
100 * as opposed to blobs
101 * - glFlushMappedBufferRange will emit a memcpy only for the flushed range
102 * (whereas previously it would emit a memcpy for the whole mapped range)
