This allows dark applications to visually integrate more nicely in Windows 10.
A little thing, but it really goes a long way to make programs not look out of
place and half-baked.

Towards a more direct and explicit mapping to platform hints, and more
consistent behaviour across platforms. OpenGL applications are generally
expected to be explicit about hints like this.

As evidence that this was confusing, the documentation for these was an
outright lie, and I've burned quite a bit of time in the past few days trying
to rework things based around that flawed understanding.
These names make it clear what these events actually are. If we need actual
create/destroy events with a broader scope, they'll have to be added, but I
suspect those aren't actually useful anyway.

This implements a more powerful protocol for working with clipboards, which
supports datatype negotiation, and fixes various issues by mapping more
directly to how things work on X11.
|

Actual window sizes and positions fit easily in a 16-bit integer. So, we use
that in "representation contexts" like events. This makes structures smaller,
and allows the values to be converted to float, double, or integer without
casting (since any int16_t or uint16_t value can fit in them without loss).
Setter APIs use native integers for convenience, to avoid casting hassles when
doing arithmetic. Ranges are checked at runtime.

Numerous things warn about this, and it's generally a bad idea to put these in
the code since it can result in incompatibly compiled code being linked
together. Unfortunately this makes building manually (without the build
system) more fiddly, but such is life.

This allows the application to control how recursive loops are handled rather
than have Pugl impose behavior which can get in the way. For example, an
application may not want to continuously animate while being resized, or set up
its rendering differently in this situation. For example, with Vulkan, setting
up a different swapchain can be necessary for smooth performance while live
resizing on Windows, and Pugl has no ability to do this.
I think it was a mistake to add this timer to Pugl itself, because it was
always a bit of a leaky abstraction, and not very appropriate for a library
that is supposed to be a thin abstraction layer. Though it almost seemed like
things ran as usual while resizing on Windows and MacOS, the main event loop
being stalled can be confusing, and there was no way to detect this. This way,
applications must explicitly handle this situation and can implement the
behavior they want without Pugl getting in the way.
This also simplifies the Pugl implementation a bit, which is always nice.

Not really sure why I used a web link here (maybe because it's more stable),
but this is more conventional.

Compilers are allowed to choose signed or unsigned for enums, and apparently
gcc and c++ make different choices.

These old "notify" names are a smell from X11 which is a bit strange and
inconsistent here, since nearly everything is a "notification" of sorts. I
think the new names here are much more clear since they are consistent with the
keyboard focus events.

The previous separation between polling and dispatching was a lie, especially
on MacOS where it is impossible to only poll for events without dispatching
anything. Providing such an API is misleading, and problematic in various
other ways.
So, merge them into a single puglUpdate() function which can do the right thing
on all platforms. This also adds the behaviour of actually processing all
events in the given time interval, which is almost always what clients actually
want to do when using a positive timeout (naively doing this before caused
terrible input lag).

This event makes it possible to send an arbitrary event to a view, which is
useful for many things. In particular, this method of communication with views
will wake up the event loop, unlike hacks in applications that share data in
some other way.
|
|
These can be used to do things when a view is created or destroyed, in
particular set up the GL context in a more controlled way. Map and unmap
events are also added for when views are shown and hidden so application can
react to this as well.
Towards the deprecation of puglEnterContext() and puglLeaveContext(), which are
prone to abuse.
squash! Remove client event stuff
