Subject: qcam: viewfinder_gl: Store textures in an array
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In preparation for RGB formats support, store the three Y, U and V
textures in an array. This makes the code more generic, and will avoid
referring to an RGB texture as textureY_.
