800835d081 Revert "text/v2: rename Glyph -> Cluster" 
This reverts commit f0d23de3d3.

Reason: Cluster doesn't represent a cluster but a part of a cluster.

f0d23de3d3 text/v2: rename Glyph -> Cluster 
This also changes AppendClusters to return cluster info even if a
cluster doesn't have a glyph.

2bad1b928f text/v2: remove Metadata.Monospace 
Apparently calculating to detection whether a face is monospace or not
is pretty heavy as this might iterate all the glyphs.

20c216b2b1 text/v2: bug fix: glyph image sizes might not be enough 
Hajime found that one glyph 'ら' was not rendered correctly in a
vertical Japanese text in examples/texti18n. This was due to an
incorrect calculation of the image sizes.

This change fixes this issue by always adding +1 to the sizes no matter
what the glyph size is or the position is. It is in theory possible to
determine whether this addition is necessary, but this is pretty
complicated and might cause other issues.
