Default textures to non-renderable.
TRAC #11309 * Lift getRenderTarget() into base class Texture. * Add pure virtual convertToRenderTarget() and getSurface(). Author: Andrew Lewycky Signed-off-by: Shannon Woods Signed-off-by: Daniel Koch git-svn-id: https://angleproject.googlecode.com/svn/trunk@54 736b8ea6-26fd-11df-bfd4-992fa37f6226
