Fix missing characters or assert with certain font sizes
The alphaMapBoundingBox() only exists to prefetch the size of rendered alpha maps, to reserve space in the glyph cache. Since 104e6d0f5427f5ebaab106b1651eb76c4c56df98 we have not used the QPainterPath fallback code path when actually rendering the glyphs, but that patch neglected to update the code that retrieved the bounding box. This could in some cases cause a mismatch, and if the alpha map we ended up with in the end was larger than the reserved space, this could trigger an assert or an empty spot in the cache. [ChangeLog][Text][Freetype] Fixed an issue where characters would in some rare cases be missing from text, depending on font metrics, font size and system scale factor.
