Add proper detection for maximum texture and renderbuffer size

Trac #13849 Increased the maximum possible texture & renderbuffer size to 16384 (the minimum required for DX11 cards). Limit the actual maximum texture & renderbuffer size to the maximum that it reported by the underlying D3D9 device. Note that creating textures and renderbuffers at the maximum size will quickly exhaust video memory!
