//
// From the GLSL ES 3.00 specification, section 4.5.4 ("Default
// Precision Qualifiers"):
//
// "The precision statement
//
// precision precision-qualifier type;
//
// can be used to establish a default precision qualifier. The
// type field can be int or float or any of the sampler types, and
// the precision-qualifier can be lowp, mediump, or highp."
//
// Section 8 (Built-In Functions) of the GLSL ES 1.00 spec says:
// "uniform lowp sampler2D sampler;
// highp vec2 coord;
// ...
// lowp vec4 col = texture2D (sampler, coord);
// // texture2D returns lowp"
//
// Section 4.5 (Precision and Precision Qualifiers) of the GLSL 1.30
// spec also says:
//
// "Precision qualifiers are added for code portability with OpenGL
// ES, not for functionality. They have the same syntax as in OpenGL ES."
//
// From this, we infer that GLSL 1.30 (and later) should allow precision
// qualifiers on sampler types just like float and integer types.
//
// This test verifies that a precision qualifier can be used on all of
// GLSL 1.30's sampler types.
