Timer queries are significantly more efficient, are synchronized to CPU time, and the synchronized frame numbering makes it possible to correlate stuff in the Timeline view
- New powerful scrolling Timeline view for seeing all time events across all threads
- Redo flame graph to use stack-based nesting rather than the standard collector nesting
- Rewrite flame graph drawing to not use labels
- Status bar appears in main window showing top-level level collectors; double-clicking them brings up their chart and right-clicking them shows their children
- Context menus are added when right-clicking labels and charts
- Tooltips now appear when mouse hovers over collector area in a chart
- Strip chart windows now automatically determine the appropriate scale better
- Graph menus redone to allow opening flame chart anywhere as well as strip chart
- Instead of just ms everywhere, also use s / us / ns where appropriate
- Don't disable smoothing right away on mouse down on strip chart, only after dragging
- Windows: The MDI child windows are quite ugly and overlap with the status bar, so instead they are now top-level windows, but some code is added to make them spawn inside and move with the parent window, and minimize to its corner. I can back this out if people prefer the old behavior despite the ugly decoration
- Windows: Label text shows ellipsis when cut off
- Windows: Graph windows no longer have icons
- Windows: Graph windows no longer spawn perfectly on top of each other, rather cascading
- GTK: Render at high resolution when GDK_SCALE is not 1
- GTK: Graph windows are forced to be floating in tiling WMs
- GTK: Flame chart window no longer has useless dividing bar
- GTK: Use more efficient cairo surface types
- "App:Show code:General" is gone, it was causing too much trouble
- Replace odd "Client::GuiObjects" with "Nodes:GUI"
- Regroup "Dirty PipelineCyclers" underneath "PipelineCyclers"
Partial backport of 07545bc9e318d1799ceabe8838d04d7ad9297a45 for Windows, requires building with `--override USE_MEMORY_MIMALLOC=1 --override USE_DELETED_CHAIN=UNDEF` for optimum effect
We don't need the extra precision, in fact it is detrimental to restoring build caches in a cross-platform way.
This commit will invalidate all current build caches.
Cherry-picked from 2a904f398592ce7effedc4f12720be0cef9b6cc9 (see #1260)
For experimentation only - it's disabled by default unless you also specify --override USE_MEMORY_MIMALLOC=1 (I did not see a discernable benefit over glibc, but more experimentation is warranted, especially with older glibc versions)

Windows' malloc has awful performance. mimalloc is orders of magnitude faster, even faster than DeletedBufferChain. Therefore, only enable USE_DELETED_CHAIN on Windows when building without mimalloc.
On Linux, mimalloc doesn't appear to be measurably faster than glibc's own allocator. Both are marginally than DeletedBufferChain, though, and substantially faster in the multi-threaded case, so USE_DELETED_CHAIN is disabled there in all cases.
Speedup is realised by using thread-local variables. Note that on Windows we can't inline get_current_thread, but it's still faster this way than calling TlsGetValue.
In theory the cache line alignment should help avoid false sharing but I have not profiled that extensively.
* New "Flame Graph" chart for seeing all collectors in a frame, much easier to read than piano roll
* Update controls, fonts, background color to more modern visual style on Windows
* Proper support for high DPI monitors (with correct scaling)
* Add tooltips for collector labels showing full name and averaged value
* Colors of collectors are now converted to sRGB transfer encoding
* Major performance improvement to piano roll view on Windows
* Movering mouse over labels now highlights the corresponding area in chart
* Label hover effect changed to darkening effect instead of border
* Reimplement graph as static common control on Windows
* Check boxes are now clickable by their label on Windows
* Graph windows have minimum sizes on Windows
Useful for uniquely identifying the process in a situation where multiple clients on the same host connect with the same server.
New version bump is not necessary, as old servers should just ignore the extra field in the datagram.
This typedefs to std::atomic<> when building with true threading, and uses a dummy implementation without.
This lets us use the full range of atomic operations offered by C++11, including explicit specification of memory fences. Using barriers lets the compiler generate more optimal code since currently we are using the quite strict sequential-consistent memory ordering for all operations. ReferenceCount has been changed to use the correct barriers (I hope). This may especially make a difference on weak ordering systems such as ARM.
Over time we should gradually replace the use of AtomicAdjust with the new patomic file.
Now behaves consistent with other applications (tested with Logitech MX Master 3 for Mac on macOS 10.13 in unnatural scrolling configuration).
Set `cocoa-invert-wheel-x true` to revert to old behaviour.
This causes an annoying "this app would like to receive keystrokes from any application" alert to be shown
Enable iokit-scan-mouse-devices or iokit-scan-keyboard-devices to restore the old behavior
