#12064: PETKA: Subtitles "jump" (have different line heights)
--------------------+-------------------------------------------
Reporter:  Tkachov  |      Owner:  (none)
    Type:  defect   |     Status:  new
Priority:  low      |  Component:  Engine: Petka
 Version:           |   Keywords:  subtitles, jump, line heights
    Game:  Petka 1  |
--------------------+-------------------------------------------
 In the original game subtitles have fixed line height, thus they always
 appear at the same Y position. In ScummVM text labels jump from one Y
 position to another depending on line height, which looks weird.

 Video demonstration: https://youtu.be/HHFUXRGwwKc (first 23 seconds are in
 ScummVM, the other are in the original).

 Because of that multiline subtitles also look strange: the gap between two
 lines changes depending on the lines text.

 Another minor issue which probably doesn't deserve a separate ticket: in
 ScummVM multiline subtitles are left-aligned, while in the original game
 these were centered.

 In the attachments:
 - **01_*** - superscript baselines for subtitles in ScummVM and original
 game;
 - **02_*** - same, but for multiline subtitles;
 - **03_*** - shows left align (ScummVM) vs. centered (original game);
 - **petka1-ru.s17** and **save2.dat** are ScummVM and original game save
 files for the dialogue from the video;
 - **petka1.s17** and **save3.dat** are ScummVM and original game save
 files for the dialogue from the **03_*** screenshots.
