5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * How this works:
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * In general it is not so easy like on the other platforms, cause Cocoa
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * doesn't support any clipping of already painted stuff. In Mac OS X there is
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * the concept of translucent canvas's e.g. windows and there it is just
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * painted what should be visible to the user. Unfortunately this isn't the
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * concept of chromium. Therefor I reroute all OpenGL operation from the guest
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * to a frame buffer object (FBO). This is a OpenGL extension, which is
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * supported by all OS X versions we support (AFAIC tell). Of course the guest
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * doesn't know that and we have to make sure that the OpenGL state always is
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * in the right state to paint into the FBO and not to the front/back buffer.
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * Several functions below (like cocoaBindFramebufferEXT, cocoaGetIntegerv,
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * ...) doing this. When a swap or finish is triggered by the guest, the
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * content (which is already bound to an texture) is painted on the screen
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * within a separate OpenGL context. This allows the usage of the same
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * resources (texture ids, buffers ...) but at the same time having an
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * different internal OpenGL state. Another advantage is that we can paint a
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * thumbnail of the current output in a much more smaller (GPU accelerated
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * scale) version on a third context and use glReadPixels to get the actual
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * data. glReadPixels is a very slow operation, but as we just use a much more
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * smaller image, we can handle it (anyway this is only done 5 times per
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * Other things to know:
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * - If the guest request double buffering, we have to make sure there are two
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * buffers. We use the same FBO with 2 color attachments. Also glDrawBuffer
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * and glReadBuffer is intercepted to make sure it is painted/read to/from
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * the correct buffers. On swap our buffers are swapped and not the
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * - If the guest request a depth/stencil buffer, a combined render buffer for
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * this is created.
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * - If the size of the guest OpenGL window changes, all FBO's, textures, ...
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * need to be recreated.
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * - We need to track any changes to the parent window
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * (create/destroy/move/resize). The various classes like OverlayHelperView,
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * OverlayWindow, ... are there for.
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * - The HGCM service runs on a other thread than the Main GUI. Keeps this
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * always in mind (see e.g. performSelectorOnMainThread in renderFBOToView)
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * - We make heavy use of late binding. We can not be sure that the GUI (or any
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * other third party GUI), overwrite our NSOpenGLContext. So we always ask if
5a07658d13590eba51dd98ef335a73d2a11edaa7vboxsync * this is our own one, before use. Really neat concept of Objective-C/Cocoa
