ANativeWindow getWidth/Height does not detect any changes when using
Vulkan, so use the old onContentRectChanged callback to get notified
when size changed. Use those values instead when figuring out how large
swapchain to create.
Tested trivially on Galaxy S9+ Exynos model.
== DETAILS
For users upgrading--particularly via the online updater--we should
smoothly migrate them to the new name. If the "media" directory
exists and the "assets" directory doesn't, then rename "media" to
"assets".
== TESTING
none yet
- task_content.c, load_content_from_compressed_archive: fix use after free
- platform_win32/uwp: fix frontend_..._get_powerstate never returning FRONTEND_POWERSTATE_NONE
- platform_win32/uwp: fix whitespace
- cheevos.c: fix potential use after free in a loop, just to be save
- only use filestream_exists immediately before filestream_delete or
any other genuine filestream-related operations - when just checking
if a path exists on the filesystem, just use path_is_valid - faster
So this makes two basic changes:
1. Add a few extra dirs, hide root dir in the filesystem
2. Simplify the default dir selection code so it doesn't take three code blocks to change a dir
A few of the decisions here were weird.
This shouldn't affect anything for end users and makes the code more mantainable.
