+// This file overrides most of the standard built-in functions that operate on vec4 data type.
+// This file also overrides most commonly used functions that do not neccessarily operate
+// on vec4 data type, like dot(vec3,vec3). Those are adapted to vec4 instructions and are believed
+// to execute faster.
+// This file replaces parts of the core.gc and common.gc, so it must be included somewhere after
+// the common.gc file.
+// 
+// Assembly instructions required:
+//   float_to_vec4
+//   vec4_add
+//   vec4_subtract
+//   vec4_multiply
+//   vec4_divide
+//   vec4_negate
+//   vec4_dot
