43     producing motion vectors that convey the 2D transformation from a reference
44     image to a target image.  There are various uses of motion estimation, such as
47     This extension adds support for motion estimation in OpenGL ES by adding
49     output texture containing the corresponding motion vectors.
91     are called to perfom the motion estimation based on the contents of the two input
92     textures, <ref> and <target>.  The results of the motion estimation are stored in
100     The resulting motion vectors are stored in a 2D texture <output> of the format GL_RGBA16F,
108     Each texel in the <output> texture represents the estimated motion in pixels, for the supported
110 …generate sub-pixel motion vectors, in which case the returned vector components may have fractional
111     values.  The motion vector X and Y components are provided in the R and G channels respectively.
112     The B and A components are currently undefined and left for future expansion.  If no motion is
114     the R and G channels will be set to zero, indicating no motion.
120     motion estimation will not be performed for the corresponding block.  Any non-zero texel value
121     will produce a motion vector result in the <output> result.  The <mask> only controls the vector
166     (2) Why use GL_RGBA16F instead of GL_RG16F for storing the motion vector output?
173     (3) Why is the motion estimation quality not defined?
