... instead of tools::Rectangle. Several problems were there: 1. First, a horizontal bounding rectangle was calculated, with due rounding; and then the result was rotated, and after that, rounded again. That made the resulting rotated rectangle coordinates very imprecise. 2. Also, ceil/floor was applied without normalization; and in case of rotated font, that meant, that sometimes the range could be not expanded to cover partially covered pixels, but instead collapsed. 3. The rotation to angles other than 90 degree multiples was done incorrectly, resulting in cut off parts of characters. 4. For 90 degrees, the imprecise result of sin/cos converted 0.0 into values like 3e-16, which then could be ceil'ed up to 1. Using B2DRectangle and its transform allows to simplify and fix the calculations easily, and avoids premature rounding. Render of rotated text of small size is more stable with this change.
