+ * Public API for querying Angelica's GL call redirections.
+ * <p>
+ * Angelica's bytecode transformer redirects GL calls (e.g., {@code GL11.glPushMatrix()}) to
+ * {@link com.gtnewhorizons.angelica.glsm.GLStateManager GLStateManager} for state tracking and
+ * core profile compatibility. This works for normal Java bytecode loaded through the Forge classloader,
+ * but callers that bypass class transformation (e.g., Nashorn/script engines, reflection, MethodHandles)
+ * need to perform their own redirection.
+ * <p>
+ * This class provides the redirect mapping data and a precompiled regex pattern for transforming
+ * script source text before evaluation.
+ *
+ * <h3>Example: transforming a Nashorn script before eval</h3>
+ * Given a script that uses {@code importPackage(Packages.org.lwjgl.opengl)} and calls
+ * {@code GL11.glPushMatrix()}, the text transformation rewrites those calls before evaluation:
+ * <pre>{@code
+ * // Make GLStateManager available to the script -- either via importPackage:
+ * script = "importPackage(Packages.com.gtnewhorizons.angelica.glsm);\n" + script;
+ * // ... or via Java.type for an explicit binding:
+ * // script = "var GLStateManager = Java.type('" + GLRedirects.TARGET_CLASS + "');\n" + script;
+ *
+ * // Rewrite: GL11.glPushMatrix() -> GLStateManager.glPushMatrix()
+ * script = GLRedirects.getMethodRedirectPattern().matcher(script).replaceAll(mr -> {
+ *     String target = GLRedirects.getTargetMethodName(mr.group(0));
+ *     return target != null ? "GLStateManager." + target : mr.group(0);
+ * });
+ *
+ * engine.eval(script);
