+ How to wrap the R coordinate. One of PIPE_TEX_WRAP_*.
+
+The wrap modes are:
+
+* ``PIPE_TEX_WRAP_REPEAT``: Standard coord repeat/wrap-around mode.
+* ``PIPE_TEX_WRAP_CLAMP_TO_EDGE``: Clamp coord to edge of texture, the border
+ color is never sampled.
+* ``PIPE_TEX_WRAP_CLAMP_TO_BORDER``: Clamp coord to border of texture, the
+ border color is sampled when coords go outside the range [0,1].
+* ``PIPE_TEX_WRAP_CLAMP``: The coord is clamped to the range [0,1] before
+ scaling to the texture size. This corresponds to the legacy OpenGL GL_CLAMP
+ texture wrap mode. Historically, this mode hasn't acted consistantly across
+ all graphics hardware. It sometimes acts like CLAMP_TO_EDGE or
+ CLAMP_TO_BORDER. The behaviour may also vary depending on linear vs.
+ nearest sampling mode.
+* ``PIPE_TEX_WRAP_MIRROR_REPEAT``: If the integer part of the coordinate
+ is odd, the coord becomes (1 - coord). Then, normal texture REPEAT is
+ applied to the coord.
+* ``PIPE_TEX_WRAP_MIRROR_CLAMP_TO_EDGE``: First, the absolute value of the
+ coordinate is computed. Then, regular CLAMP_TO_EDGE is applied to the coord.
+* ``PIPE_TEX_WRAP_MIRROR_CLAMP_TO_BORDER``: First, the absolute value of the
+ coordinate is computed. Then, regular CLAMP_TO_BORDER is applied to the
+ coord.
+* ``PIPE_TEX_WRAP_MIRROR_CLAMP``: First, the absolute value of the coord is
+ computed. Then, regular CLAMP is applied to the coord.
