+/**
+ * A replacement for the sine angle lookup table used in {@link MathHelper}, both reducing the size of LUT and improving
+ * the access patterns for common paired sin/cos operations.
+ *
+ * sin(-x) = -sin(x)
+ * ... to eliminate negative angles from the LUT.
+ *
+ * sin(x) = sin(pi/2 - x)
+ * ... to eliminate supplementary angles from the LUT.
+ *
+ * Using these identities allows us to reduce the LUT from 64K entries (256 KB) to just 16K entries (64 KB), enabling
+ * it to better fit into the CPU's caches at the expense of some cycles on the fast path. The implementation has been
+ * tightly optimized to avoid branching where possible and to use very quick integer operations.
+ *
+ * Generally speaking, reducing the size of a lookup table is always a good optimization, but since we need to spend
+ * extra CPU cycles trying to maintain parity with vanilla, there is the potential risk that this implementation ends
+ * up being slower than vanilla when the lookup table is able to be kept in cache memory.
+ *
+ * Unlike other "fast math" implementations, the values returned by this class are *bit-for-bit identical* with those
+ * from {@link MathHelper}. Validation is performed during runtime to ensure that the table is correct.
