-History
-21-03-2010
-- The define GLB_DELPHI dosn't check versions anymore. If you say you are using delphi
- then it's your problem if that isn't true. This prevents the unit for incompatibility
- with newer versions of Delphi.
-- Problems with D2009+ resolved (Thanks noeska and all i forgot)
-- GetPixel isn't set if you are loading textures inside the constructor (Thanks Wilson)
-10-08-2008
-- AddAlphaFromglBitmap used the custom pointer instead the imagedatapointer (Thanks Wilson)
-- Additional Datapointer for functioninterface now has the name CustomData
-24-07-2008
-- AssigneAlphaToBitmap overwrites his own palette (Thanks Wilson)
-- If you load an texture from an file the property Filename will be set to the name of the file
-- Three new properties to attach custom data to the Texture objects
- - CustomName (free for use string)
- - CustomNameW (free for use widestring)
- - CustomDataPointer (free for use pointer to attach other objects or complex structures)
-27-05-2008
-- RLE TGAs loaded much faster
-26-05-2008
-- fixed some problem with reading RLE TGAs.
-21-05-2008

+ 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, ...) }
