60a58d4d8d [client] all: make it possible to signal full window invalidation 
Now that we are drawing with damage rects, when the window is hidden and
then exposed the window may not get fully redrawn. This provides
`app_invalidateWindow` for the display server backend to call when the
screen needs a full redraw.

df0397b10b [client] imgui: track last rectangles for overlays 
This is necessary in case overlays change size. When this happens, we must
damage the larger of the overlays' rectangles this frame and last frame.
This erases the overlay from where it is no longer appears.

In order to do this, we must keep track of the rectangles for every overlay
with no exception. We cannot short-circuit the generation of rectangles if
we run out of buffer space, and we must allocate space for MAX_OVERLAY_RECTS
rectangles for every frame. Otherwise, we will not know where to erase the
overlay if it disappears.

563ad18f4e [client] egl: improve cursor damage logic 
1. Use atomics and return exact cursor positions from egl_cursor_render
   to avoid race conditions between cursor render and update.
2. Instead of messing with lastCursorValid in various overlays, simply use
   the hasOverlay/hadOverlay logic for cursor damage. This simplifies the
   logic greatly.

As a result, I believe all cursor-related artifacts are fixed.

Note to reviewer: as atomic_init and atomic_store are implemented as macros,
it is currently not possible to pass structs as compound literals due to the
comma being interpreted as an argument separator by the preprocessor.

headers. Also, we now use GL_EXT_buffer_storage for MAP_PERSISTENT_BIT_EXT
and MAP_COHERENT_BIT_EXT as the core versions are only available in desktop
OpenGL 4.4. Similarly, we need GL_EXT_texture_format_BGRA8888 for GL_BGRA_EXT
as GL_BGRA is desktop-only.

ba6f26393f [client] egl: add framework for multiple scaling algorithms 
This commit fixes the issues with the meaning of useNearest being flipped
by removing the variable and use enumerations.

We define an enumeration EGL_DesktopScaleType to express the type of scaling
needed to be performed: no scaling, upscaling, or downscaling. This is
updated when either the frame size or the viewport size changes.
Previously, we only updated the useNearest when the frame size changes.

The desktop shader can now support an enumeration of scaling algorithms,
although only nearest and linear are currently implemented.

Like before, nearest is used when not scaling or upscaling, and linear is
used when downscaling.

30a888711b [client] egl: force DMA copy into texture in on_frame 
This commit forces the DMA'd memory to be copied into the texture in
the EGL on_frame handler. This avoids tearing when the LG host inevitably
updates the underlying memory. We need an additional copy inside the GPU,
but this is cheap compared to copying from system memory.

We could have used logic to lock the memory buffer, but that would require
performing DMA on every frame, which wastes memory bandwidth. This
manifests as reduced frame rate when moving the mouse compared to the
non-DMA implementation.

We also keep multiple EGLImages, one for each DMA fd, to avoid issues
with the OpenGL driver.

a46a3a2668 [all] use explicit void parameter lists 
This makes it a compile-time error to call a function that semantically
takes no parameters with a nonzero number of arguments.

Previously, such code would still compile, but risk blowing up the stack
if a compiler chose to use something other than caller-cleanup calling
conventions.

1ca5e439c1 [client] egl: disable EGL when running on Wayland 
This commit makes Looking Glass always use the OpenGL renderer when
running on Wayland. The EGL renderer is broken on Wayland and can't
reasonably be fixed until SDL is dropped entirely (as per
https://github.com/gnif/LookingGlass/issues/306).

Until that time, the OpenGL renderer provides a much better
Wayland-native experience.

4bceaf5505 [client] fix hang in eglSwapBuffers when exiting while not visible 
eglSwapBuffers is allowed to block when called with a nonzero interval
parameter. On Wayland, Mesa will block until a frame callback arrives.
If an application is not visible, a compositor is free to not schedule
frame callbacks (in order to save CPU time rendering something that is
entirely invisible).

Currently, starting Looking Glass from a terminal, hiding it
entirely, and sending ^C will cause Looking Glass to hang joining the
render thread until the window is made visible again.

Calling eglDestroySurface is insufficient to unblock eglSwapBuffers, as
it attempts to grab the same underlying mutex.

Instead, this commit makes it so that we pass a 0 interval to
eglSwapBuffers when running on Wayland, such that we don't block waiting
for a frame callback. This is not entirely ideal as it *does* mean
Looking Glass submits buffers while hidden, but it seems better than
hanging on exit.

It also forces opengl:vsync and egl:vsync flags to off when running on
Wayland, as they are meaningless there.

[How]
Replace eglGetDisplay() with eglGetPlatformDisplay(). Requires EGL 1.5, but should
be supported with any desktop driver released in the past few years.

bca54ab1f6 [client/host] added new asyncronous memory copy 
This changes the method of the memory copy from the host application to
the guest. Instead of performing a full copy from the capture device
into shared memory, and then flagging the new frame, we instead set a
write pointer, flag the client that there is a new frame and then copy
in chunks of 1024 bytes until the entire frame is copied. The client
upon seeing the new frame flag begins to poll at high frequency the
write pointer and upon each update copies as much as it can into the
texture.

This should improve latency but also slightly increase CPU usage on the
client due to the high frequency polling.

695822bd6d [client] redesign of the renderer archiceture for mt support 
This is the first of two commits that completely turn the rendering code
on it's head. This change set decouples the guest's capture rate from
the host's render rate for both cursor and frame updates. This helps
prevent the host application from stalling when waiting for frame draws
when all it want's to do is send cursor updates.

* Breaks OpenGL-Basic for now

c38e38d43d [client] opengl: add splitmouse option 
This feature was previously hardcoded enabled, it is now optional as
some hardware pipelines stall with the excessive flushes resulting in a
jumpy cursor. Default is disabled and may be re-enabled with
`-o opengl:splitmouse=1` or `-o opengl-basic:splitmouse=1` depending on
the renderer selected.

This is based on bf8da7fd7e4397fe9931e82e52753806f1eee7e0 by @kiljacken
Per issue #11 on some cards this method performs much better then the
persistant buffering used in the standard OpenGL renderer.

Closes #11

9c03327701 [client] opengl: added back double buffering and vsync support 
This adds back in double buffering and vsync support. This has been
carefully implemented so that the render function blocks until the video
card reports that it has advanced a frame, this ensures that the OpenGL
pipeline never buffers frames.
