dee14a0a9e clients/simple-dmabuf-egl: Add some notes when using direct-display
protocol

As dmabuf uses a different coordinate (top-left) system than OpenGL
(bottom-left) using both direct-display with the Y_INVERT dmabuf attrib
flag would result in the image being inverted (direct-display will
remove the Y_INVERT flag, which caused the image to be displayed
correctly). Notifies users that direct-display is in use.

95efe82982 simple-dmabuf-egl: Allow QueryDmaBufModifiers to report no modifiers
Some drivers expose the extension so they can expose
eglQueryDmaBufFormatsEXT, but don't support any modifiers. Treat this the
same as if the extension wasn't present.

1ca4ed2015 clients: fix len-string formatting
All these have the printf format string wrong. "%*s" sets the field width but
does not limit the string to len bytes. You need to set precision instead to
limit to len bytes: "%.*s".

Found by grepping, after wondering why my WIP prints printed garbage at the
end.

ecbdcfd373 Rename zalloc.h to libweston/zalloc.h
It is a public installed header used by libweston.h.

See "Rename compositor.h to libweston/libweston.h" for rationale.

ff98a9080f clients/simple-dmabuf-egl: Properly check for error in gbm_bo_get_handle_for_plane
gbm_bo_get_handle_for_plane returns handle.s32 == -1 on error, at least
for the Mesa dri implementation.

10a7339611 clients/simple-dmabuf-egl: Create the EGL display using the GBM platform
Since we are managing and rendering to buffers on our own with GBM,
create the EGL display using the GBM platform with the DRM render node,
instead of using the Wayland EGL platform.

7261edfe36 clients: Add a mandelbrot set shader to simple-dmabuf-egl
Support drawing a mandelbrot set in the fragment shader, rendering it
with separate draw calls, one for each cell in a virtual 4x4 grid. This
more complex and heavy drawing will potentially help us to visually
discover any present or future explicit synchronization issues.

The mandelbrot set rendering is enabled with the -m/--mandelbrot
command-line switch.

uncover rendering issues (e.g. modifier-related issues) which may not be

b100668426 clients: Add simple-dmabuf-egl
Add a client that uses EGL/GLESv2 to draw to dmabuf buffers, utilizing
EGLImages and FBOs. The client uses GBM to create the dmabufs buffers.

The simple-dmabuf-egl client is partly based on patch [1] that changes
dmabuf clients to use GBM instead of libdrm code, but has been greatly
simplified since in this case we don't require direct pixel access or
non-RGBA formats.
