[Spice-devel] [Xspice PATCH 07/11] uxa: fix compiler warnings (initialize width, height, [xy]Dst_copy)

[Uri Lublin]

Some compiler warnings for example:
uxa-glyphs.c:1045: warning: ‘width’ may be used uninitialized in this function
uxa-glyphs.c:1045: warning: ‘height’ may be used uninitialized in this function
uxa-render.c:1090: warning: ‘xDst_copy’ may be used uninitialized in this function
uxa-render.c:1090: warning: ‘yDst_copy’ may be used uninitialized in this function

I think these can never actually happen as the code protects use of
those uninitialized variables, but I'd not "argue" with the compiler.
