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.

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).

text: make CacheGlyphs create all the sub-pixel variations (#2530) 
Before this change, CacheGlyphs created only necessary glyphs wihtout
considering variations by sub-pixels in X direction. This was sometimes
unexpected when a user might want to prepare glyph cache with a string
including all the letters, instead of actual texts.

This change makes CacheGlyphs create all the sub-pixel variations of
the given runes.

a042af98b1 text: improve rendering quality with HintingVertical 
When HintingVertical is used, the interval between two glyphs is not
quantized (i.e. not a whole pixel). The text package didn't consider
this situation.

This change improves the quality by using more various glyph images
with 1/4 pixels granularity in vertical direction.

5ec05ed79d text: Cleaning up the cache after the rendering finishes 
Before this fix, cleaning up the cache happens during making glyph
images, and this can be problematic when the text includes more
glyphs than the cache limit.

After this fix, Draw allows to have more glyph cache than the limit
temporarily.

text: Add MeasureString method (#1152) 
(sorta-kinda continuation from #1151)

This PR adds a MeasureString(string, font.Face) method next to the Draw() method in Ebiten's
text package. It should work with any supported font.Face, even "non-standard" faces like
those produced by packages like https://github.com/AndreKR/multiface. MeasureString's code
was adapted from the Draw method, so it's just as reliable.
