| | | | | | | | | | | | | | | | | | | | X11GLXGraphicsConfiguration.GLXFBConfig2GLCapabilities(..) X11GLXGraphicsConfiguration.GLXFBConfig2GLCapabilities(..) ran over all FB configs and for each it grabbed native config values separately. Fetching them in bulk mode saves around 7% of this function's cost. Also reuse XRenderPictFormat instance for 'XRenderDirectFormat XRenderFindVisualFormat(..)' call, saving a few NIO creation cycles w/ StructAccessor. Biggest savior is X11GLXGraphicsConfigurationFactory.chooseGraphicsConfigurationFBConfig()'s fast path w/o chooser and usable 1st FBConfig. Here we only issue 'GLXFBConfig2GLCapabilities(..)' on the first valid entry. Test w/ 50 X11GLXGraphicsConfigurationFactory.chooseGraphicsConfigurationFBConfig() invocations: - pre change: 1.708 ms - post change: 650 ms Time is no spent almost solely on native glXChooseFBConfig (546ms).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux - No compatibility GLProfile (GL2, >= GL3bc) Fix GL Version Validation: We shall not rely on our known good versions when validating a queried GL context version, but allow some 'room' for a higher version post JOGL release while still cutting off 'odd versions'. While GL version detection, we always iterate from the highest known version down to the lowest. Hence 'GLContext.isValidGLVersion(..)' is satisfied by validating the lowest version number but allowing a higher than known one. Now we would return 'invalid' for a version >= 6. It is enough to clip to the maximum known version when iterating, allowing the highest unknown version to be available. GLContext.isValidGLVersion(..): Returns true, if the major.minor is not inferior to the lowest valid version and does not exceed the highest known major number by more than one. The minor version number is ignored by the upper limit validation and the major version number may exceed by one. The upper limit check is relaxed since we don't want to cut-off unforseen new GL version since the release of JOGL. Hence it is important to iterate through GL version from the upper limit and 'decrementGLVersion(..)' until invalid. Add GL Version 4.4 to valid known versions. Remove ES3 desktop detection, which is impossible Regression of commit 3a0d7703da32e9a5ddf08a334f18588a78038d88 (ES3 support)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We processed MouseEvents within NEWT as follows: sendMouseEvent/enqueueMouseEvent -> doMouseEvent, - called by native code to be delivered via consumeMouseEvent (now or later) - events are validated (move/drag, boundaries) - missing events are synthesized (click, enter, ..) as well as in several factories, i.e.: - AWTNewtEventFactory (1:1) - AndroidNewtEventFactory - synthesized events .. (click, ..) - android typed gesture detection (drag -> 1 finger scroll..) The latter enqueues events do Window/Display directly to be consumed by WindowImpl. Then users may have their own gesture detection etc. +++ This change unifies mouse/pointer event processing within NEWT within consumeEvent(..) which represents a common entry point. Gesture processing is now realized w/ a public API - GestureHandler - GestureHandler.GestureListener - GestureHandler.GesureEvent which supplies: - default impl. of optional gesture handlers (scroll, .. - default: enabled) - public API to add/remove gesture-handler and -listener +++ This allows our impl. to scale better in support of more multiple pointer devices (-> Win7/Win8, X11, ..).
