lawnjelly 3c69377f10 2d Legacy - close vulnerabilities and more debug checks ...

While adding more debug checks to legacy renderer, I closed 2 types of vulnerabilities:

* TYPE_PRIMITIVE would previously read from uninitialized data if only specifying a single color
* Other legacy draw operations would fail in debug AFTER accessing out of bounds memory rather than before

Many calls to glBufferSubData are wrapped in a safe version which checks for out of bounds and exits the draw function if this is detected.
