- * From section 4.5.2 of the GLSL 1.30 spec:
+ * Section 4.5.2 (Precision Qualifiers) of the GLSL 1.30 spec says:
* "Any floating point or any integer declaration can have the type
* preceded by one of these precision qualifiers [...] Literal
* constants do not have precision qualifiers. Neither do Boolean
* variables.
*
- * In GLSL ES, sampler types are also allowed.
+ * Section 4.5 (Precision and Precision Qualifiers) of the GLSL 1.30
+ * spec also says:
*
- * From page 87 of the GLSL ES spec:
- * "RESOLUTION: Allow sampler types to take a precision qualifier."
+ * "Precision qualifiers are added for code portability with OpenGL
+ * ES, not for functionality. They have the same syntax as in OpenGL
+ * ES."
+ *
+ * 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"
+ *
+ * From this, we infer that GLSL 1.30 (and later) should allow precision
+ * qualifiers on sampler types just like float and integer types.
