/**
* XXX THIS IS OBSOLETE - drivers should take care of detecting window
* size changes and act accordingly, likely calling _mesa_resize_framebuffer().
*
* GL_MESA_resize_buffers extension.
*
* When this function is called, we'll ask the window system how large
* the current window is. If it's a new size, we'll call the driver's
* ResizeBuffers function. The driver will then resize its color buffers
* as needed, and maybe call the swrast's routine for reallocating
* swrast-managed depth/stencil/accum/etc buffers.
* \note This function should only be called through the GL API, not
* from device drivers (as was done in the past).
