-// Texture related functions are here !
-//
-// The texture handling is heart and soul of this gpu. The plugin was developed
-// 1999, by this time no shaders were available. Since the psx gpu is making
-// heavy use of CLUT (="color lookup tables", aka palettized textures), it was
-// an interesting task to get those emulated at good speed on NV TNT cards
-// (which was my major goal when I created the first "gpuPeteTNT"). Later cards
-// (Geforce256) supported texture palettes by an OGL extension, but at some point
-// this support was dropped again by gfx card vendors.
-// Well, at least there is a certain advatage, if no texture palettes extension can
-// be used: it is possible to modify the textures in any way, allowing "hi-res"
-// textures and other tweaks.
-//
-// My main texture caching is kinda complex: the plugin is allocating "n" 256x256 textures,
-// and it places small psx texture parts inside them. The plugin keeps track what
-// part (with what palette) it had placed in which texture, so it can re-use this
-// part again. The more ogl textures it can use, the better (of course the managing/
-// searching will be slower, but everything is faster than uploading textures again
-// and again to a gfx card). My first card (TNT1) had 16 MB Vram, and it worked
-// well with many games, but I recommend nowadays 64 MB Vram to get a good speed.
-//
-// Sadly, there is also a second kind of texture cache needed, for "psx texture windows".
-// Those are "repeated" textures, so a psx "texture window" needs to be put in
-// a whole texture to use the GL_TEXTURE_WRAP_ features. This cache can get full very
-// fast in games which are having an heavy "texture window" usage, like RRT4. As an
-// alternative, this plugin can use the OGL "palette" extension on texture windows,
-// if available. Nowadays also a fragment shader can easily be used to emulate
-// texture wrapping in a texture atlas, so the main cache could hold the texture
-// windows as well (that's what I am doing in the OGL2 plugin). But currently the
-// OGL1 plugin is a "shader-free" zone, so heavy "texture window" games will cause
-// much texture uploads.
-//
-// Some final advice: take care if you change things in here. I've removed my ASM
-// handlers (they didn't cause much speed gain anyway) for readability/portability,
-// but still the functions/data structures used here are easy to mess up. I guess it
-// can be a pain in the ass to port the plugin to another byte order :)
