 /** 

 Gets the generic capabilities of the accelerator, including which display modes 

 are supported for the bitmap passed to NewL().

 Generic capabilities apply to all software graphics accelerators on the device. 

 The function is static, so it can be used to find out the capabilities of 

 graphics accelerators before deciding on whether or not to create one.

 The CGraphicsAccelerator::Capabilities() function provides information about 

 the capabilities of a particular graphics accelerator.

 As capabilities may vary depending on the display mode of a bitmap, this method 

 should indicate as supported any features which are only available in some 

 display modes.

 @return Generic capabilities for software graphics accelerators.
