Function get_block_count_safe

Source/astcenc_mathlib.h:516–530

* @brief Get the number of blocks along a single axis. * * This function is implemented so that intermediate values will not overflow, * which may occur when input values are not trusted. Implementation is * obviously slower than one that does not do this, so don't use for values * we know cannot overflow. * * @param dim_axis The axis dimension, in pixels. * @param dim_block The block

 * @return The number of blocks needed in this dimension.
