It will now check all layers of a material.
Additionally it will also delete all descriptor sets of Vulkan hardware textures before precaching to make sure that nothing here can accidentally still reference a deleted texture.
Now, all menus will use the same scale, i.e. it only depends on the screen width and a base size of 640. This nearly universally yields better results than trying to make a 320x200 screen fit.
The only exceptions to this are the intermission screens and the level summary. These, unlike the menu need to try to make a 320x200 screen fit, but without all the hackery that was present to adjust the menu display.
Note that since this affects globally visible script variables, both the intermission and summary drawers will not use their own set but instead temporarily override the global setting as long as they run their own code.
Changing the use of variables here might cause much worse problems with menu code so it wasn't attempted
Since this needs to do cursor positioning calculations it's the one spot in the entire engine where UTF-8 would simply be to messy, especially when having to deal with double wide characters.
* re-added screen blends for images from the hardware renderer.
* moved all postprocessing of the image out of the renderers.
* cleaned out a large piece of cruft for handling the palette in the frame buffer class. This was all a remnant of the old paletted backend that no longer exists. Nowadays the screen blend is just a postprocessing effect drawn over the 3D screen, there is no need to maintain any of it as global state anymore.
* since the engine doesn't produce paletted screenshots anymore there is no need to have handling for it in the generation code. This depended on otherwise obsolete information so it got removed along with that information.
This will mostly ensure that each patch used for composition is only loaded once and automatically unloaded once no longer needed.
So far only for paletted rendering, but the same logic can be used for true color as well.
- changed PARAM_STRING to use the passed string by reference instead of by value. The 3 instances where passing by value was needed now use PARAM_STRING_VAL.
For the varargs functions that used the Type field to validate their parameters, now a hidden additional argument is passed which contains a byte array with the type info for the current call's arguments. Since this is static per call location it can be better prepared once when the code is being compiled instead of being put in a runtime created array for each invocation. Everything else uses the per-function instance of the same data.
The only thing that still needed the type field with a VMValue is the defaults array, so this uses a different struct type now to store its data.
Most importantly, the separate command line options for switching on the legacy buffer handling have been removed.
There's really no need for them anymore, because unlike in earlier versions many of the implementation differences no longer exist - with the exception of where the light and vertex buffer contents are generated.
For testing this, -glversion 3 is sufficient.
