+ *\r
+ * when modifying or extending this file, several things must be taken into consideration:\r
+ * - when adding new operators that were marked as reserved in the initial specification,\r
+ * one must only uncomment particular lines of code that refer to operators being added;\r
+ * - when adding new shader target, one must reserve new value for shader_type register and\r
+ * use it in .if constructs for symbols that are exclusive for that shader;\r
+ * - some symbols mimic output of other symbols - the best example is the "for" construct:\r
+ * expression "for (foo(); ; bar())" is seen as "for (foo(); true; bar())" by the output\r
+ * processor - hence, special care must be taken when rearranging output of essential symbols;\r
+ * - order of single-quoted tokens does matter in alternatives - so do not parse "<" operator\r
+ * before "<<" and "<<" before "<<=";\r
+ * - all double-quoted tokens are internally preprocessed to eliminate problems with parsing\r
+ * strings that are prefixes of other strings, like "sampler1D" and "sampler1DShadow";\r
