wanted convolution or dithering kernels.

of slightly overkill Image objects.

Lock/Unlock mechanism safer, and implement the rule of three.

requires stuff from lol/math, too.

Camera & vector.cpp : Fixed shifted_perspective crash with almost zero FOV.

Added utils.h : GetRandom(Array<T>) : gets a random element in a template list with weight logic.
                T FindValue(char*) : Find the value of a safe enum from the given name (when GetName is implemented)

such as alpha blending, depth test, etc.

to get M_PI from the platform headers and cast it to float.

positive values, and add a unit test for rand<int>.

crashing from an assertion failure.
