+/*
+    This cache stores internal Qt shader programs in shared memory.
+
+    This header file is ugly on purpose and can only be included once. It is only to be used
+    for the internal shader cache, not as a generic cache for anyone's shaders.
+
+    The cache stores either ShaderCacheMaxEntries shader programs or ShaderCacheDataSize kilobytes
+    of shader programs, whatever limit is reached first.
+
+    The layout of the cache is as outlined in the CachedShaders struct. After some
+    integers, an array of headers is reserved, then comes the space for the actual binaries.
+
+    Shader Programs are identified by the md5sum of their frag and vertex shader source code.
+
+    Shader Programs are never removed. The cache never shrinks or re-shuffles. This is done
+    on purpose to ensure minimum amount of locking, no alignment problems and very few write
+    operations.
+
+    Note: Locking the shader cache could be expensive, because the entire system might hang.
+    That's why the cache is immutable to minimize the time we need to keep it locked.
+
+    Why is it Meego specific?
+
+    First, the size is chosen so that it fits to generic meego usage. Second, on Meego, there's
+    always at least one Qt application active (the launcher), so the cache will never be destroyed.
+    Only when the last Qt app exits, the cache dies, which should only be when someone kills the
+    X11 server. And last but not least it was only tested with Meego's SGX driver.
+
+    There's a small tool in src/opengl/util/meego that dumps the contents of the cache.
