/**
* Native bindings to the NV_transform_feedback extension.
*
* This extension provides a new mode to the GL, called transform feedback, which records vertex attributes of the primitives processed by the GL. The
* selected attributes are written into buffer objects, and can be written with each attribute in a separate buffer object or with all attributes
* interleaved into a single buffer object. If a geometry program or shader is active, the primitives recorded are those emitted by the geometry program.
* Otherwise, transform feedback captures primitives whose vertex are transformed by a vertex program or shader, or by fixed-function vertex processing.
* In either case, the primitives captured are those generated prior to clipping. Transform feedback mode is capable of capturing transformed vertex data
* generated by fixed-function vertex processing, outputs from assembly vertex or geometry programs, or varying variables emitted from GLSL vertex or
* geometry shaders.
*
* The vertex data recorded in transform feedback mode is stored into buffer objects as an array of vertex attributes. The regular representation and the
* use of buffer objects allows the recorded data to be processed directly by the GL without requiring CPU intervention to copy data. In particular,
* transform feedback data can be used for vertex arrays (via vertex buffer objects), as the source for pixel data (via pixel buffer objects), as program
* constant data (via the NV_parameter_buffer_object or EXT_bindable_uniform extension), or via any other extension that makes use of buffer objects.
*
* This extension introduces new query object support to allow transform feedback mode to operate asynchronously. Query objects allow applications to
* determine when transform feedback results are complete, as well as the number of primitives processed and written back to buffer objects while in
* transform feedback mode. This extension also provides a new rasterizer discard enable, which allows applications to use transform feedback to capture
* vertex attributes without rendering anything.
*
* Requires {@link GL15 OpenGL 1.5}.
