Elias Naur 1eaa5dd15e app,app/internal/gpu: process frame in parallel
A frame ops buffers is tracersed twice: once for GPU commands,
and once for everything else. There is already a GPU goroutine for
concurrentl issuing of GPU commands; move the frame ops processing
to the goroutine as well. Both frame ops passed can then proceed
in parallel.

Elias Naur 97299dc2f9 op/paint: make every ImageOp unique
The gioui.org/commit/74407a50d598bfd27e8f8e48b6832cc5df04de77
added a NewImageOp constructor that always copies the supplied
image. It does that for two reasons:

First, the image.Image reference is used in the image=>texture
map of cached textures. Without a copy, we wouldn't detect a
modified image even if a new ImageOp was created.

Second, we don't want the program to touch the image while the GPU
is uploading it.

The second reason was removed in a previous change that blocks
FrameEvent.Frame until we're done with the operations, including
uploading images to the GPU.

The first reason is easily fixed by using a unique per ImageOp,
as pointed out by Alessandro Arzilli.

This change switches to using the unique key. Alessandro's patch
avoids the copy when possible.

Denis Bernard 68063633f2 app/internal/window: Fix keyboard handling on X11
When the control key is pressed, clear event.state bits before calling
Xutf8LookupString in order to get the unmodified key name. This allows
proper handling of all keys in combination with ModCommand.

`key.Event.Name` is however layout dependent. Client code should be
careful about this when picking key shortcuts like CTRL-'+': on a QWERTY
keyboard, only CTRL-'=' and CTRL-SHIFT-'=' are generated when pressing
the '=' key of the top row. The keypad '+' key generates events with
`Name = '+'` as expected.

Elias Naur 396a538afe app/internal/window: don't second guess UI scale
Before this change, Gio tries hard to come up with a reasonable UI scale
factor on desktop OSes derived from the physical dimensions and
resolution of connected monitors. Gio also attempts to detect the user
specified system UI scale and apply it.

However, all that is complex and misguided:

- The UI scale should not depend on whatever monitor is connected at
program startup - For multiple monitors, it's unclear which one to base
the scale off.  - Applying both a monitor derived scale *and* the user
specified scale is wrong, because the user scale is relative to some
fixed scale, not Gio's derived scale.  - With an automatic scale, Gio
does not respect user preference and will not have a similar scale to
other programs on the desktop.

Get rid of the the automatic UI scale detection and rely only on the
user scale.

Elias Naur 5eeaadccea app/internal/window: apply font scale to dp scaling on Wayland
As discussed in gio#53, Linux font scales conflate two settings: the fractional
UI scale and the user preference as a result of conditions such as impaired
vision. The former setting should apply to both dps and sps, while the latter
only to sps. However, with the assumption that more users presumable change the
font scale for the former reason rather than the latter, we should apply the
font scale to both dps and sps in Gio.

On Xephyr, when fitst entering x11Window.loop(), syscall.Ppoll would
block forever while XPending() would still return a non zero value.
This commit refactors the loop so that XPending() gets called first,
then fallback to waiting in ppoll if there are no pending draw events.

This has the added benefit of reducing the number of calls to ppoll when
receiving a lot of events.

Elias Naur 4a26bdad5d cmd/gogio: build for iOS/macOS without -fmodules and -fobjc-arc
The `gogio` tool adds the `-fmodules -fobjc-arc` flags to the Cgo
C flags. Unfortunately, that masks problems where Cgo packages
accidentally didn't have the flags in their #cgo directives such
as package log.

Move the flags so they're only explicitly mentioned when `gogio`
invokes the host compiler to build the `main.m` shim.

Fix package log to include the missing flags.

While we're here, silence OpenGL ES deprecation warnings on iOS, just
as we do for macOS. The warnings are normally not visible because
the gogio tool suppress output from the go tool.
