cc: Make UV coords in TileDrawQuad a full RectF
Previously, TileDrawQuad assumed that texels were 1:1 with geometry, so it only
needed an offset into the texture to calculate the UVs. For impl-side painting
where multiple contents scales might be in play, a given texture rect isn't going
to be 1:1 with geometry rects and also will not be necessarily integer aligned.
Also, some things (like edge antialiasing) still need to know the texture size
so that it can do half-texel offsets, so this new texture rect needs to stay in
"texel space" rather than 0-1 "uv space".
