-##  Gradle start up script for UN*X
-##
+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
+#

-+ * 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.
