BUG=skia:5932
Original CL description:
>
>Limit GL_TEXTURE_RECTANGLE filtering to bilinear.
>
>Adds a clamp for GrTexture filtering that can be set by a subclass at construction. The clamping is performed by GrTextureParams. GrGLTexture limits filtering to bilinear for rectangle and external textures.
>
>Also moves samplerType() to GrTexturePriv from GrTexture.
>
