+Shader parameters for DP's own features:\r
+- dp_reflect <r> <g> <b>\r
+ Makes surfaces of this shader reflective with r_glsl_water. The reflection is\r
+ additive. When the color isn't specified, it defaults to white (full\r
+ reflection). If only one color component is specified, it counts as a grey\r
+ value.\r
+- dp_refract <refractmin> <refractmax> <distort> <r> <g> <b>\r
+ Marks a surface as "water" for r_glsl_water, that is, add a refraction\r
+ component too. The refraction amount (see dp_reflect) is at most refractmax\r
+ (when looking straight into it) and at least refractmin (when looking parallel\r
+ to the surface). The default distort is multiplied by distort. The color\r
+ modulates the refraction component. refractmin defaults to 0 when unspecified,\r
+ all others default to 1. If only one color component is specified, it counts\r
+ as a grey value.\r
