Shyotl e756140e1d Innitial commit of experimental v2 texture system port work. Compiles and runs on windows, at least. Fixing bugs as they come.
Need to test:
localassetbrowser
preview related floaters
hgfloatertexteditor
maps
media textures! Currently very hacky
web browser
alpha masks on avatars
bumpmaps
Are all sky components appearing?
LLViewerDynamicTexture (texture baking, browser, animated textures, anim previews, etc)
Snapshot related features
Customize avatar
vfs floater
UI textures in general
Texture priority issues

/**
* @file lltexture.h
* @brief LLTexture definition
*
* This class acts as a wrapper for OpenGL calls.
* The goal of this class is to minimize the number of api calls due to legacy rendering
* code, to define an interface for a multiple rendering API abstraction of the UI
* rendering, and to abstract out direct rendering calls in a way that is cleaner and easier to maintain.
