>#
># Test that vertex shader defaults to highp (only fragment shader
># needs to specify float precision) and that later fragment shader
># highp precision declaration overrides earlier mediump declaration.
>#
># Otherwise, Mesa triggers precision mismatch linker check.
>#
># Shader is extracted from Glmark2 ES variant, and Glmark2 is
># under GPL3, so this is too.
