split tex code into (file format specific) loaders and opengl texture ops like upload() This was SVN commit r601. 2004-06-26 00:18:03 +02:00			`#ifndef OGL_TEX_H__`

- split up lib/res into file, graphics and sound. - wposix.cpp: initial support for MEM_RESERVE and MEM_COMMIT semantics in mmap - cstr: removed no longer necessary serialization header - xmlutils: wrap new() calls in nommgr/mmgr; allows tracking other allocs in this file. - add u64_from_u32 - various minor comments/improvements. This was SVN commit r2604. 2005-08-12 19:06:53 +02:00			`#include "../handle.h"`
- both tex.cpp and ogl_tex.cpp had functions named tex_* - confusing. renamed to ogl_tex* to disambiguate. - ogl_tex_bind now supports multitexturing (avoids need to get id and then bind manually) - provide nicer API for querying texture properties (no longer one big getter). improved GUI determination of texture alpha. - renderer: another see-if-texture-has-alpha and fixed alpha map code (wasn't checking if all are same size. only worked because the first map was larger than the rest This was SVN commit r2647. 2005-09-02 04:54:02 +02:00			`#include "lib/types.h"`
hook up emulate_glCompressedTexImage2D to new tex transform code (which takes care of DDS unpack) to that end, provide support for "wrapping" existing textures so that tex_* and ogl_tex* calls may be used. also have renderer use ogl_tex for its created-on-the-fly composite alpha texture also named atlas's thread (for fun+profit during debugging) This was SVN commit r2754. 2005-09-20 00:48:20 +02:00			`#include "lib/ogl.h"`
