Add glclear in texture2DProgram

[uberspot]

Hello :)

Just a small suggestion.
In Texture2DProgram in the draw method before it starts drawing it should do

    GLES20.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT);

To clear the buffer and not leave residues from previous draws.

That works if you're only drawing one thing (e.g. filling a window with video). Not so good if you're drawing multiple shapes -- see draw() in "Hardware scaler exerciser" for an example.

Ah yes in that case nevermind. :) I'm closing this one then.
