Bug 1037 - FBObject/GLFBODrawable: Do not assume using a TextureAttachment for a Colorbuffer, also make DEPTH optional.

API Change

+++

In certain cases a TextureAttachment for the FBO's color buffer
is not desired, either for performance reasons where texture functionality
is not required or to avoid texture restrictions like size, etc.

+++

GLFBODrawable shall use TextureAttachment for the FBO's color buffer
and a DEPTH buffer per default.
However, the user shall be allowed to use a plain ColorAttachment (renderbuffer)
and also no DEPTH buffer.

+++

FBObject Details:
 - Colorbuffer interface exposes Attachment details
   like format, size, etc as well as it's implementation
   specifics, isTextureAttachment() and getTextureAttachment() allowing a clean cast and type query.

 - Allow ColorAttachment to be used for non MSAA

 - Make TextureAttachment optional for method 'use(GL, TextureAttachment)'

 - Only validate size against MAX_TEXTURESIZE if using a TextureAttachment

 - API Change:
   - rename: getColorAttachmentCount() -> getColorbufferCount()
   - add: getTextureAttachmentCount()
   - change 'TextureAttachment getSamplingSink()' -> 'Colorbuffer getSamplingSink()'
