return;
}
IntRect tileRect = tileImage->image()->rect();

patternData->pattern = Pattern::create(tileImage->image(), true, true);
return;
}
// Draw the first cell of the pattern manually to support overflow="visible" on all platforms.
int tileWidth = static_cast<int>(patternData->boundaries.width() + 0.5f);
int tileHeight = static_cast<int>(patternData->boundaries.height() + 0.5f);
// Don't create ImageBuffers with image size of 0
if (!tileWidth || !tileHeight) {
