This issue was previously fixed in 0c2ed71cdd, but that change added a bug that would trigger an infinite loop on scrolling in a list without any selectable items. Then 4fdbe81a13 restored the old behavior, reintroducing the issue.
This new fix does handle lists without any selectable items correctly.
This is just a small consistency fix: DI_SCREEN_LEFT_CENTER and DI_SCREEN_RIGHT_CENTER exist, so, logically, similar combo flags should exist for DI_ITEM as well.
This is needed for implementing reliable serialization of custom translations. As long as they are merely ints they cannot be restored on loading a savegame because the serialization code does not know that these variables are special.
GZDoom used to have hardcoded MessageBox menu selector, 0x0d character
of console font, while the other menu is displayed is SmallFont.
It looked too ugly if SmallFont and ConFont heights are different,
and also there was no method of modifying the selector.
Now, the selector is 0x0d from SmallFont, if SmallFont contains this glyph
(its height is greater than zero), otherwise it falls back to previous
behavior (using ConFont as a source of this glyph).
To define custom MessageBox menu selector, just define 0x0d glyph for
SmallFont, and it will be displayed in the menu.
The gap between selector and menu options text is 3 pixels (as before), and
if you wish to enlarge this gap, just add some transparent columns at the
right side of 0x0d glyph.
Due to undefined downconversion rules from double to int, there is no way to safely downcast the return from MSTimef, meaning the function is completely useless for retrieving integral time stamps.
The old version is essential for these cases and must be kept around.
* Emit a warning when relational comparisons are made between signed and unsigned ints.
* Handle shift operators so that they do not fail for constant definitions.
* changed return type of Array::Size() to signed int as most code out there is using it this way and would otherwise drown in warnings.
* fixed a few deprecation warnings.
