RE_Texture* RE_IconTextureCache::addMipMapTexture	(	RE_Render *	r,
		PXL_Raster *	texture
	)

Add a texture from a raster, and automatically generate the mip-map levels for it.

RE_Texture* RE_IconTextureCache::addMipMapTexture	(	RE_Render *	r,
		const UT_Array< PXL_Raster * > &	levels
	)

Add a mip-mapped texture, with many levels defined by the rasters passed as levels, and return its unique ID. The levels must all be powers of two in size, and must follow the progression from 2^Nx2^N, 2^(N-1)x2^(N-1), ..., 1x1.

RE_Texture* RE_IconTextureCache::addTexture	(	RE_Render *	r,
		PXL_Raster *	texture
	)

Add a regular texture from a raster and return its unique ID.

void RE_IconTextureCache::beginTextureDefer ( RE_Render * r )

These methods record the textures to be drawn, and draws them all at once when endTextureDefer() is called. If you need all cached textures to be drawn immediately without doing an end, call flushTextureDefer().

void RE_IconTextureCache::clearTextureCache ( )

Free all textures.

void RE_IconTextureCache::endTextureDefer ( RE_Render * r )

void RE_IconTextureCache::flushTextureDefer ( RE_Render * r )

int RE_IconTextureCache::getTextureVersion ( ) const

inline

Returns a version # for the cache; every time it is cleared, this number is bumped;

void RE_IconTextureCache::removeTexture ( RE_Texture * tex )

Remove a texture from the cache.

void RE_IconTextureCache::renderTexture	(	RE_Render *	r,
		int	x,
		int	y,
		int	w,
		int	h,
		RE_Texture *	tex,
		float	alpha,
		float	z
	)

Render a given texture at (x, y) with width and height w, h.
