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.

ca8a2896b4 text/v2: performance optimization by using image.RGBA
Apparently, image.RGBA doesn't use the slow path at draw.Draw, which
is called from a rasterizer's Draw.

StdFace was used as a cache key, then these are never released.

This change fixes this issue by adding faceCacheKey and use it as

911cf0c48c text: deprecate BoundString
After we found a correct definition of the term 'dot', BoundString seems
less useful than expected. In order to adjust the position of a text, we
should use a face's Metrics and a string's advance (font.MeasureString).
