+ The glBitmap is a Delphi/FPC unit that contains several wrapper classes
+ to manage OpenGL texture objects. Below you can find a list of the main
+ functionality of this classes:
+ - load texture data from file (e.g. BMP, TGA, DDS, PNG, JPEG, ...)
+ - load texture data from several other image objects (e.g. TBitmap, TLazIntfImage, SDL Surface)
+ - save texture data to file (e.g. BMP, TGA, DDS, PNG, JPEG, ...)
+ - save texture data to several other image objects (e.g. TBitmap, TLazIntfImage, SDL Surface)
+ - support for many texture formats (e.g. RGB8, BGR8, RGBA8, BGRA8, ...)
+ - manage texture properties (e.g. Filter, Clamp, Mipmap, ...)
+ - upload texture data to video card
+ - download texture data from video card
+ - manipulate texture data (e.g. add alpha, remove alpha, convert to other format, switch RGB, ...) }
