manage texture-buffer-backed data arrays shared within a context
This is the texture-buffer analog of vtkOpenGLVertexBufferObjectCache. The vertex-pulling mappers (vtkOpenGLLowMemoryPolyDataMapper via vtkDrawTexturedElements / vtkOpenGLArrayTextureBufferAdapter) reconstruct every vertex in-shader from data bound as samplerBuffer texture objects. Historically each adapter owned its own texture, so the same vtkDataArray (positions, normals, colors, connectivity, ...) rendered through several mappers — composite, glyph, LIC, or simply many actors sharing one polydata — was uploaded once per mapper. This cache lets those mappers share a single uploaded texture buffer.
Entries are keyed on the composite (array, scalarComponents, integerTexture): not the array pointer alone, because the same array may legitimately be uploaded with different layouts (e.g. a 3-component position array bound as RGB tuples versus as scalars). Each entry stamps the array MTime at which it was uploaded so a mutated array is lazily re-uploaded.
The cache is owned by vtkOpenGLState (one per context), reachable via vtkOpenGLRenderWindow::GetArrayTextureBufferCache(), mirroring GetVBOCache().
