86b50cc8ab [client] imgui: initialize keymap
This allows ImGui to understand some of the basic key presses.

Also moved the include guard from kb.c to kb.h where it actually makes sense.

f1b1da60ea [client] imgui: improve method for high DPI
We now give ImGui the true logical size of the window and tell it to scale
the framebuffer. To fix the blurry fonts, we continue to load fonts at the
scale necessary for the DPI and use FontGlobalScale to shrink the fonts back
to the logical size. The font rectangle is then expanded by the framebuffer
scaling, resulting in good text rendering.

This method has the advantage of not messing up the sizes of resizable
overlays when moving across monitors.

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.

00c2773e6b [client] ds: separate grab and capture logic
Currently, (un)grabPointer is used both for tracking/confining the mouse

d0a12f6097 [client] ds: detect when the cursor exits into an overlapping window

update along with the translated local guest cursor position. This makes
it possible for the display server to keep the local cursor position in

270631f1b9 [client] ds: add surface-only warp variant
This commit converts the output of ds->getProp(LG_DS_WARP_SUPPORT) to
an enum containing three items:

* LG_DS_WARP_NONE: warp is not supported at all
* LG_DS_WARP_SURFACE: warp is possible, but only inside the window
* LG_DS_WARP_SCREEN: warp is possible anywhere on the screen

LG_DS_WARP_NONE corresponds to the old false return value, and
LG_DS_WARP_SCREEN corresponds to the old true return value.

LG_DS_WARP_SURFACE is designed for Wayland, where warping is possible,
but only in our window. In this case, since we cannot warp outside
the window, we can warp the cursor to the edge when we attempt to exit.
If the cursor leaves, the normal leave routine gets called, and the
cursor disappears. If the cursor does not end up leaving, we grab it
again.

1a407a67b1 [client] input: add releaseKeysOnFocusLoss option
This makes dealing with window manager shortcuts that overlap with guest
keys more pleasant, while retaining the previous functionality for users
who prefer it.

For instance, previously, using Alt+Tab (or $mod as Alt in i3/sway
movement commands) would result in the guest retaining Alt as pressed.

When the guest regained focus, it would continue thinking Alt is
pressed, leading to accidentally triggering obscure shortcuts. One had
to remember to press Alt again to "unstick" things, which was
suboptimal.

0c9ecdfcb5 [client] wm: optionally disable screensaver when requested in guest
This commit adds a new option, win:autoScreensaver, which when set to yes,
automatically disables the screensaver when requested by an application
running in the guest, and enables it when the application no longer wants
it disabled.

This is useful when doing media playback in the guest.

06f6a96b56 [client] spice: fix input:grabKeyboardOnFocus
It appears that the keyboard should only be grabbed if the client is
focused and the cursor is in the view. However, the relevant logic was
missing from core_setCursorInView, and the keyboard was never actually
grabbed.

This commit adds the call to g_state.ds->grabKeyboard(), allowing grabbing
to work.

89b73512ad [client] renderer: add ability to toggle the FPS display
Before, if you want to see the FPS, you need to close the client and
restart it with the -k switch to see the FPS. This is annoying.

This PR introduces a new keybind, ScrollLock+D, which, when pressed,
toggles the display of the FPS.

This is implemented for both EGL and OpenGL backends.

b0f9d2f713 [client] spice/wayland: improve cursor tracking logic
One of the major issues with the old tracking code is a data race
between the cursor thread updating g_cursor.guest and the
app_handleMouseBasic function. Specifically, the latter may have
sent mouse input via spice that has not been processed by the guest
and updated g_cursor.guest, but the guest may overwrite g_cursor.guest
to a previous state before the input is processed. This causes some
movements to be doubled. Eventually, the cursor positions will
synchronize, but this nevertheless causes a lot of jitter.

In this commit, we introduce a new field g_cursor.projected, which
is unambiguously the position of the cursor after taking into account
all the input already sent via spice. This is synced up to the guest
cursor upon entering the window and when the host restarts. Afterwards,
all mouse movements will be based on this position. This eliminates
all cursor jitter as far as I could tell.

Also, the cursor is now synced to the host position when exiting
capture mode.

A downside of this commit is that if the 1:1 movement patch is not
correctly applied, the cursor position would be wildly off instead
of simply jittering, but that is an unsupported configuration and
should not matter.

Also unsupported is when an application in guest moves the cursor
programmatically and bypassing spice. When using those applications,
capture mode must be on. Before this commit, we try to move the guest
cursor back to where it should be, but it's inherently fragile and
may lead to scenarios such as wild movements in first-person shooters.

Unless the corresponding mouse down event was on our surface, we should

This is always the case on Wayland. On some other platforms,
SDL_CaptureMouse can be used to obtain input that happens outside the

function.

We may want to process a mouse up if the corresponding mouse down
initiated a drag (e.g., of a window) that was released slightly outside
of the Looking Glass surface. Previously, Looking Glass would ignore the
mouse up, and the guest would be confused into thinking the button had
never been released, not ending the drag.
