e6df0acad9 [common] vector: eliminate double allocation when possible 
This commit creates two constructor/destructor pairs for vector:
* vector_alloc/vector_free dynamically allocates the vector itself
* vector_create/vector_destroy uses existing Vector objects

bb91b41c64 [client] egl: look at 3x3 around the pixel instead of 4x4 
Using 4x4 means that some pixels will be outside of the lanczos window. The
ideal lanczos function should in fact be zero in those areas, so we shouldn't
waste time processing those pixels.

I can't notice any difference in the results.

b7d3bbbd82 [client] egl: use standard-compliant way of EGL detection 
According to the documentation for eglQueryString:

> EGL_BAD_DISPLAY is generated if display is not an EGL display connection,
> unless display is EGL_NO_DISPLAY and name is EGL_EXTENSIONS.

Therefore, we should check EGL by doing:

    eglQueryString(EGL_NO_DISPLAY, EGL_EXTENSIONS)

Indeed, the old way of eglQueryString(EGL_NO_DISPLAY, EGL_VERSION) works on
libglvnd but not using mesa's libEGL.so directly.

Also added a warning to make it more obvious that EGL is not available.

After the damage queue PR, EGL damage count 0 means no change, and -1 means
invalidate the entire window. However, several other places have different
semantics, and we are not handling them correctly:

1. KVMFR uses 0 to signal invalidating the entire frame, so if we receive 0
   rectangles in egl_on_frame, we should set damage count to -1.
2. The damage overlay treated 0 as full damage, which is now incorrect. This
   is fixed, and now it treats 0 as no update, and -1 as full damage.

The way things were handled in EGLTexture is not only very hard to
follow, but broken. This change set breaks up EGLTexture into a modular
design making it easier to implement the various versions.

Note that DMABUF is currently broken and needs to be re-implemented.

134829cbf2 [client] imgui: make graph y-axis configurable

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.
