eglmesaext-include.patch

webkit-gtk relies on EGL/eglmesaext.h header. This header is indirectly included via EGL/eglext.h when building against mesa. But this is not the case with headers provided by libglvnd.

Build error:

/tmp/portage/net-libs/webkit-gtk-2.24.4/work/webkitgtk-2.24.4/Source/WebKit/UIProcess/gtk/WaylandCompositor.cpp: In member function ‘void* WebKit::WaylandCompositor::Buffer::createImage() const’:

  134 |     return static_cast<EGLImageKHR*>(eglCreateImage(PlatformDisplay::sharedDisplay().eglDisplay(), EGL_NO_CONTEXT, EGL_WAYLAND_BUFFER_WL, m_resource, nullptr));
      |                                                                                                                    ^~~~~~~~~~~~~~~~~~~~~   

Attached patch fixes this issue for me.
