Thanks to OpenGL's messed up state system this didn't cause some clear failure but just reused the last bound buffer instead which may not have had a matching size.
This was done because the backdrop as implemented was the only texture in the entire game that had to be deleted and recreated each frame.
However, with Vulkan this would have necessitated quite a bit of synchronization with the render pipeline which wasn't really feasible just for this one single texture.
Now the texture manager can assume that once a texture was created it will be immutable and never has to change.
This was a relic from trying to support ZDoomGL's texture shader system but would make texture management with Vulkan significantly more complicated because it would require dynamic descriptor set management for textures which can cause a lot of overhead.
MAP07 - Dropping onto the outdoor lava will now raise triangle sectors.
Should be impossible to get stuck in them now.
MAP08 - Fix (what I presume to be an unintentional) missing texture.
With this, one can use its self-replacement code (which copies a bunch of its state into the replacement actor, and monitors for boss death if appropriate), but select the replacement class based on some other criteria (map number, the player's RPG stats, the player's class, etc).
Previously, a RandomSpawner with infinite recursion would hang the game, because the recursion check was happening before the recursion counter (bouncecount) was set.
Game crashed when any of gl_brightfog, gl_lightadditivesurfaces, gl_notexturefill CVARs is set with no level loaded
There was impossible to reset settings to defaults because of this
UE1: Add support for Deus Ex format vertex data.
UE1: Group triangles by skin index AND type/flags (preparation for per-surface render style support).
UE1: Add handling of Weapon Triangle (preparation for model attachment support).
UE1: Support flat shaded triangle flag.
Minimum OpenGL version is now 3.3 and so, the given legacy fallback doesn't make any sense
This increases required macOS version to 10.9 as on previous versions nothing but a black screen was rendered
