[Public WebGL] Size of GL_FLOAT

I see a lot discussion about the size of of GL_FLOAT. This is my opinion.

There is only one person that needs to know what the size of a variable is and that is the programmer that writes the program. 
He needs to know if the variable is big enough for his application. A fixed size on every platform, the same number of bytes and
preferable the same byte order is the best solution. If a hardware vendor decides to put a float into a double that is his choice 
but the interface for the programmer should be the same on every platform. There should be no gabs in buffers!!! WebGL is
based on OpenGL ES 2.0 which is targeted to portable devices where every byte counts. So please no gabs!! Waisting half the
memory because the hardware vendor uses a double instead of a float is madness! Please keep things simple.

Best regards,
