History
+20-11-2013
+- refactoring of the complete library
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
- 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
+- 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
- Property DataPtr now has the name Data
- Functions are more flexible between RGB(A) and BGR(A). RGB can be saved as Bitmap and will be saved as BGR
- Unused Depth removed
-- Function FreeData to freeing image data added
+- Function FreeData to freeing image data added
24-10-2007
- ImageID flag of TGAs was ignored. (Thanks Zwoetzen)
