r_texture_allocate

uint r_texture_allocate(PImageFormat format, uint x, uint y, uint z, boolean filter, boolean tile, void *data);

Description: Allocates an image. If z is set to 1 the image will be 2D, if the z is set to R_IB_IMAGE_CUBE a cube map is created where all six sides are x*y resolution. filter, and tiled are booleans that indicates if the resulting image should be filerd and tiled respectivly. The data pointer is a user provided pointer of data to fill up the texture. If data is set to NULL, Relinquish will generate a pattern as a defalut image to aid in debugging.
