Enabling the use of BGRA in addition to BGR #2

… adding a second texture to render.

Check this line before merging. It doesn't seem to be causing problems, but I wanted to make sure it was okay with you that I'm setting it to use GL_SRGB8_ALPHA8 instead of GL_SRGB8 in OpenGL. |

These two lines cause the error below in my environment.
/home/mohammedari/catkin_opengl2/devel/.private/opengl_ros_lib/lib/libopengl_ros_lib.so: undefined reference to `cv::_OutputArray::_OutputArray(cv::Mat&)'

Textures with the internal format of 'GL_SRGB8_ALPHA8' work with RGB input/output in my environment as I tested. It requires additional computational cost since glTexSubImage2D function converts RGB to RGBA, but it is trivial. I think it would be OK to use GL_SRGB8_ALPHA8 for internal format. Many thanks! |

Okay I deleted those lines. They were only used for debugging before. Good catch! |

As well as the option of adding a second texture to render.
