 ====== Textures ======
+Gorilla3D extends FMX texture support of TTextureBitmap. With default FMX behaviour you're only allowed to create a RGBA texture.
+===== Texture-Kinds =====
+With v0.8.2+ more texture types than 2D textures are supported.
+^Format^Description^
+|TGorillaTextureKind.Texture2D|Default texture kind creating a two dimensional image.|
+|TGorillaTextureKind.Texture3D|Creating a three dimensional texture.|
+|TGorillaTextureKind.CubeMap|Creating a texture with 6 sides of 2D Images.|
+===== Supported Formats =====
+A texture format is described by a components internal format and a general format. While the components define the exact datatypes of byte data, the general format is more a simple setup information.

+|TGorillaTextureWrap.ClampToEdge||
+|TGorillaTextureWrap.Clamp||
+|TGorillaTextureWrap.Repeated||
+|TGorillaTextureWrap.MirrorRepeated||
+===== Setting up =====
+To set up a Gorilla3D texture correctly, you need to encapsulate property configuration inside of BeginSetup and EndSetup method.
+Only then all settings will correctly be submitted to OpenGL.
+===== Example =====
