* Fix some renderbuffer reference counting issues. Also fixes a mem leak.Brian2007-03-251-1/+2

* Implement alpha buffer copy for SwapBuffers().Brian2007-03-231-0/+3
| | | | | | | | | | | | | Nicolai writes: When the pixmap pixel format has no alpha channel, the x11 driver (software rendering) adds a wrapped alpha channel on request. During SwapBuffers, this alpha channel is not copied from back to front, which means that the front buffer doesn't really contain the contents that the back buffer previously contained. A subsequent glReadPixels from the front buffer will return an incorrect result. The following patch attempts to fix this.
* Fix/improve framebuffer object reference counting.Brian2007-03-061-1/+1
| | | | | | | Use _mesa_reference_framebuffer() and _mesa_unreference_framebuffer() functions to be sure reference counting is done correctly. Additional assertions are done too. Note _mesa_dereference_framebuffer() renamed to "unreference" as that's more accurate.
* Added _mesa_remove_renderbuffer() as a counterpart to _mesa_add_renderbuffer().Brian Paul2006-05-201-0/+5
| | | | | Added _mesa_dereference_renderbuffer() to encapsulate renderbuffer reference count decrement, delete, locking.

* Major check-in of changes for GL_EXT_framebuffer_object extension.Brian Paul2005-05-041-0/+84
Main driver impacts: - new code for creating the Mesa GLframebuffer - new span/pixel read/write code Some drivers not yet updated/tested.
