VI10GetUnusedBufferSize
V = Vector
I = Image
Function that is used to manage the Vector Image feature (object that resides on some Qpaint versions).
The VI10GetUnusedBufferSize function used to get the number of unused Buffer elements.
The buffer size is specified as the number of items directly in defining the array in the configuration file. Not all array buffer will be used for drawing operations, only part of it is actually used to process transactions. The part that is not used you learn through this function.
