Use GL to render preview. To speed up the preview, we direct the decoder output to a SurfaceTexture, then draw the texture to a surface. The media rendering parameters (crop, black-border) are implemented using different vertex coordinates. The color effects are implemented using fragment shaders. Currently only three color effects are implemented, but that's all the appplication uses. Change-Id: If84439fee572ed37ea077749ef9f2bd4f78703e1
