FBObject: Simplify API (init/reset); Only issue automatic resetSamplingSink(..) if required; Fix resetSamplingSink(..), isBound(), ..

- Simplify API (init/reset)
  - use new unique methods for init and reset:
    - void init(final GL gl, final int newWidth, final int newHeight, final int newSamples)
      - does not issue resetSamplingSink(..)
    - boolean reset(final GL gl, final int newWidth, final int newHeight, final int newSamples)
      - always issues resetSamplingSink(..)

  - deprecated dual-use (init/reset):
    - boolean reset(final GL gl, final int newWidth, final int newHeight)
    - boolean reset(final GL gl, int newWidth, int newHeight, int newSamples, final boolean resetSamplingSink)

- reset(..) no more creates a dummy 'samplingSink' instance if sampling > 0,
  left up to resetSamplingSink(..)

- Track 'modified' state of FBObject,
  if size, format or any attachment has been changed since last
    - use(..)
    - syncSamplingSink(..)
    - resetSamplingSink(..)

- Only issue resetSamplingSink(..) from syncSamplingSink(..)/use(..)
  if 'modified == true'

+++

- Fix setSamplingSink(..), i.e. samplingSink state handling:
  - Validated whether given samplingSink is initialized,
    throws Exception if not.

- Fix resetSamplingSink(..)
  - resets the bound state, i.e. leaves it untouched
    - also unbinds the samplingSink

  - sampleSinkDepthStencilMismatch() also returns true if
    this.depth/stencil == null, but samplingSink is not.

  - Newly created colorbuffer/-texture matches
    exiting colorbuffer's internal-format, if exists.

  - Using simplified resetSizeImpl(..) for size mismatch

  - Simplified samplingColorSink init check

- Fix isBound()
    was: 'bound = bound && fbName != gl.getBoundFramebuffer(GL.GL_FRAMEBUFFER)'
    fix: 'bound = bound && fbName == gl.getBoundFramebuffer(GL.GL_FRAMEBUFFER)'

- Fix detachRenderbuffer(..) validates whether detachment was successful,
  similar to detachColorbuffer(..)
