This was mostly notable on a Raspberry-Pi 4 arm64, where perfromance degragated around 3x using high-freq counter. Using our well determined Clock.currentNanos() removes this overhead, back to 'easy measuring' and having a well defined 'currentNanos()' since module start. TestTextRendererNEWT00 can enable Region and Font perf-counter w/ '-perf', w/o it only uses its own counter and hence reduce the high-freq burden (64% perf win on raspi4). +++ Below numbers show that Region.addOutlineShape() perhaps needs a little performance work to allow long text to be processed in 'real time' on embedded platform.

| | | | | | | | | | | | | | | Ease GLArrayData* buffer growth. Using integer indices, i.e. GL_UNSIGNED_INT, requires us to pass a GLProfile 'hint' to the GLRegion ctor. Region.max_indices is computed in this regard and used in Region.addOutlineShape(). TODO: If exceeding max_indices, the code path needs some work. Buffer growth is eased via GLArrayData using its golden growth ratio and manually triggering growth before processing all triangles in Region.addOutlineShape(). +++ TextRegionUtil static drawText() won't clear passed Region anymore, caller has to do this if so intended.
* FFMPEGMediaPlayer: Add implementation update for FFmpeg version 4.* (Debian ↵Sven Gothel2023-02-232-22/+12
| | | | | | | | | | | | | | | | | | | | | | | 11), 5.* (Debian 12) and 6.* (Current Development trunk) From here on, libav support has been dropped. Required FFmpeg libraries to be fully matched by their major runtime- and compiletime-versions are: - avcodec - avformat - avutil - swresample Library avdevice is optional and only used for video input devices (camera). Library avresample has been removed, since FFmpeg dropped it as well in version 6.* and swresample is preferred for lower versions. The matching major-versions of each library to the FFmpeg version is documented within FFMPEGMediaPlayer class API-doc. Each implementation version uses the non-deprecated FFmpeg code-path and compilation using matching header files is warning-free.

| | | | | | | | | | | | | | | | | | | | | | | rules for OutlineShape and add get/setWinding in Outline Loop.initFromPolyline()'s Winding determination used a 3-point triangle-area method, which is insufficent for complex shapes like serif 'g' or 'æ'. Solved by using the whole area over the Outline shape. Note: Loop.initFromPolyline()'s Winding determination is used to convert the inner shape or holes to CW only. Therefor the outter bondary shapes must be CCW. This details has been documented within OutlineShape, anchor 'windingrules'. Since the conversion of 'CCW -> CW' for inner shapes or holes is covered, a safe user path would be to completely create CCW shapes. However, this has not been hardcoded and is left to the user. Impact: Fixes rendering serif 'g' or 'æ'. The enhanced unit test TestTextRendererNEWT01 produces snapshots for all fonts within FontSet01. While it shows proper rendering of the single Glyphs it exposes another Region/Curve Renderer bug, i.e. sort-of a Region overflow crossing over from the box-end to the start.

| | | | | | | | | | | | | | | | | | | | | | | | makeCurrent() call Command SetNSViewCmd sets NSOpenGLContext's NSView via [NSOpenGLContext setView:] on the main-thread as enforced since XCode 11 using SDK macosx10.15, see Bug 1398. This command is injected into OSX's main-thread @ NSOpenGLImpl.makeCurrent(long) only if required, i.e. issued only for a newly bound NSView and skipped for surface-less or offscreen 'surfaces'. This operation must be performed w/o blocking other tasks locking the NativeSurface on main-thread to complete. Since [NSOpenGLContext setView:] acquires the CGLContext lock on the main-thread, it can't be locked by the calling thread until this task has been completed. Command issuer NSOpenGLImpl.makeCurrent(long) will not acquire the CGLContext lock if this command is pending. contextMadeCurrent(true) cures the potential unlocked CGLContext by issuing a whole GLContext.release() and GLContext.makeCurrent() cycle while waiting for this command to be completed in-between. This GLContext cycle also ensures an unlocked NativeSurface.getLock() in-between, allowing potentially blocked other tasks on the main-thread to complete and hence this queued command to execute. Notable test provoking critical multithreading issues is com.jogamp.opengl.test.junit.jogl.demos.es2.newt.TestGearsES2NewtCanvasSWT. Notable test exposing issues with an unlocked CGLContext is com.jogamp.opengl.test.junit.jogl.glsl.TestGLSLShaderState02NEWT.
* OSX/SWT Testing: Drop using 'com.jogamp.newt.util.MainThread' enforcing ↵Sven Gothel2020-03-041-26/+8
| | | | | | | | | | | | | | | | | | | default test behavior SWT and OSX's UI TK have their strict threading policy we require to comply with, e.g. see Bug 1398 lately. It doesn't help using our own MainThread vehicle to move the unit test on the OS main thread, as this removes potential causes of deadlocks - which we intend to find and resolve. This patch removed using MainThread altogether from our ant unit testing recipe as well from our manual test scripts. Unit tests are no more executed on the 'main thread'. SWT tests are patched to comply with SWT's UI threading policy. We also catch violations within NewtCanvasSWT and our SWT GLCanvas to provide same behavior on all platforms.
* Bug 1398: MacOS: Perform [NSOpenGLContext setView:] on main-thread async w/o ↵Sven Gothel2020-02-241-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | blocking Set NSOpenGLContext's NSView via [NSOpenGLContext setView:] on the main-thread as enforced since XCode 11 using SDL macosx10.15, using Runnable SetNSViewCmd. This operation must be performed async w/o blocking to allow other tasks locking the NativeSurface on main-thread to complete. Further, since [NSOpenGLContext setView:] acquired the CGLContext lock, it can't be locked until this task has been completed. Worst case scenario for a late [NSOpenGLContext setView:] issuance might be corrupt initial frame(s) displayed. Since all concurrent locking is performed within JOGL, the unlocked CGLContext window risk is only academic. However, if native 3rd party toolkits take share control, we might have a situation. +++ SetNSViewCmd is issued @ makeCurrent() now as opposed to createContext(..) and associateDrawable(true). The latter was actually late as well, as it also happened after makeCurrent when updating the drawable association. It also missed setting a null NSView when detached! release() will also set a null NSView if called after associateDrawable(false). SetNSViewCmd will only be issued if the NSView has been changed, i.e. first makeCurrent() or changing the drawable. If issued, makeCurrent() will not lock the underlying CGLContext and hence allow SetNSViewCmd to perform - see above. +++ NSViewDescriptor class structure replaces the less convenient method 'getNSViewHandle(..)', exposing all collected drawable characteristics as fields. NSViewDescriptor also respects a ProxySurface's OPT_UPSTREAM_SURFACELESS mode, which results in not using any underlying NSView - similar to OPT_UPSTREAM_WINDOW_INVISIBLE. This change ensures that all surfaceless GL operations will not use any NSView.

| | | | | | | | | | | | | | | | | | | compensation like 'DPIUtil.useCairoAutoScale()' We can't use DPIUtil's 'autoScaleUp(..)' method on non-native DPI scaling platforms as it uses a scale-factor of 1f if the higher toolkit compensates, i.e. 'DPIUtil.useCairoAutoScale()'. Since NEWT uses X11 and GDI directly, which are not DPI scale-aware, we have to drop the semnatics of 'DPIUtil.useCairoAutoScale()' and merely use the actual 'deviceZoom'. This was proposed by Marcel Au in the first place. At least I understand these semantics by now. +++ Additionally NewtCanvasSWT.SWTNativeWindow needs to return the 'deviceZoomScaleUp(..)' values for returning its size in window- and pixel-units (surface).
* Bug 1421: NEWT OSX Invisible: Refining child window visibility setting, ↵Sven Gothel2020-01-141-3/+3
| | | | | | | | | | | | | | | | | | | commenting on child-window orderOut Actual small change is to have child-NSWindow to use '[myWindow orderWindow: NSWindowAbove relativeTo:..' instead of 'orderFront' in creation and use the simple 'orderFront' to set a top-level NSWindow visible. Adding comment why we can't use 'orderOut' on child-NSWindow setting it invisible, this is due to OSX 10.7 changes and testing detaching the child-window from its parent causes havoc w/ SWT at least. Hence we only issue 'mWin orderWindow: NSWindowOut relativeTo:..]' and the result is having the child-NSWindow below the application. This in turn will make it visible again when moving the application around, as this child-NSWindow will no more follow the position. Suggestion is to have this 'fake invisible' child-NSWindow to be moved out of the overal viewport (all screens).
