miLineArc(): initialize edge1, edge2
When compiling spice-common with meson/ninja under "release" mode, I get
several compiler warnings about possibly-uninitialized members. For
example:
../subprojects/spice-common/common/lines.c: In function ‘miLineArc’:
../subprojects/spice-common/common/lines.c:2167:17: error: ‘edge2.dx’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
edge->e += edge->dx; \
^~
../subprojects/spice-common/common/lines.c:2426:24: note: ‘edge2.dx’ was declared here
PolyEdgeRec edge1, edge2;
^~~~~
Initializing these structures to zero silences the warnings.
