#ifndef __QF_GL_lightmap_h

[gl] Use glGenTextures to allocate texture numbers While the scheme of using our own allocated did work just fine, fisheye rendering uses glGenTextures which caused a texture id clash and thus invalid operations (the cube map texture happened to be the same as the console background texture). Sure, I could have just "fixed" the fisheye init code, but this brings gl closer in line with glsl (which makes extensive use of glGenTextures and glDeleteTextures). This doesn't fix any texture leaks gl has (plenty, I imagine), but it's a step in the right direction.

extern int lm_src_blend, lm_dest_blend;
Clean up global symbols for the gl renderer. Where possible, symbols have been made static, prefixed with gl_/GL_ or moved into the code shared by all renderers. This will make doing plugins easier but done now for link testing.

extern GLuint gl_lightmap_textures[MAX_LIGHTMAPS];
Nuke qboolean from orbit I never liked it, but with C2x coming out, it's best to handle bools properly. I haven't gone through all the uses of int as bool (I'll leave that for fixing when I encounter them), but this gets QF working with both c2x (really, gnu2x because of raw strings).

extern bool gl_lightmap_modified[MAX_LIGHTMAPS];
[gl] Use a scrap for lightmaps This gives a rather significant speed boost to timedemo demo1: from about 2300-2360fps up to 2520-2600fps, at least when using multi-texture. Since it was necessary for testing the scrap, gl got the ability to set the console background texture, too.

[renderer] Remove namehack.h Finally. I never liked it (felt bad adding it in the first place), and it has caused confusion with function and global variable names, but it did let me get the render plugins working.

struct transform_s;
[scene] Make entity_t just an entity id for ECS This puts the hierarchy (transform) reference, animation, visibility, renderer, active, and old_origin data in separate components. There are a few bugs (crashes on grenade explosions in gl/glsl/vulkan, immediately in sw, reasons known, missing brush models in vulkan). While quake doesn't really need an ECS, the direction I want to take QF does, and it does seem to have improved memory bandwidth a little (uncertain). However, there's a lot more work to go (especially fixing the above bugs), but this seems to be a good start.
