+  Undefining this will avoid bounding box computations, which may

+  Symbol: USESTACKALLOC
+  ---------------------
+
+    If defined stack allocation routines will be used in some functions.
+
+  Allocating memory on the stack is usually more efficient than using the
+  memory manager. If a routine uses StackAllock/StackFree then it should
+  always be wrapped inside a {$W+}...{$W-} block in order to generate
+  a stack frame.
+
+  NOTE: Undefine this symbol if you get stack overflow errors.

+  Symbol: RGBA_FORMAT
+  -------------------
+
+     Assume RGBA pixel format instead of BGRA (used by e.g. OpenGL.)
+*)

+{-$DEFINE RGBA_FORMAT}
+
+(*
+  Symbol: NOHINTING
+  -----------------
+
+    Disables font hinting by default when using TextToPath() method.
+
+  It is usually preferrable to disable hinting when using a high quality
+  polygon renderer like VPR. However, hinting can sometimes improve
+  visual quality when rendering small text (text is adjusted to pixel
+  boundaries which makes it more crisp.)
+*)
+
+{$DEFINE NOHINTING}
+
+
+(*
+  Symbol: NOHORIZONTALHINTING
+  ---------------------------
+
+    Disables horizontal font hinting when using TextToPath() method.
+
+  The following should not be used in conjunction with NOHINTING.
+  It will attempt to address the problem of extreme font hinting in the
+  GDI by disabling horizontal, but keeping vertical hinting.
+*)
+
+{-$DEFINE NOHORIZONTALHINTING}
+
+
+(*
+  Symbol: USEKERNING
+  -----------------
+
+    Enables font kerning when using TextToPath() method.
+
+  Kerning is the process of adjusting the spacing between characters in a
+  proportional font, usually to achieve a visually pleasing result. However,
+  parsing for kerning pairs is quite expensive in terms of CPU usage while the
+  effect is often very little. Thus kerning is not enabled by default.
