Also add atan and mod as it's also buggy on Mac/Win with NVIDIA cards. Also, trying to minimize emulated functions by adding masks for fragment/vertex shaders.

	32e97315	2011-08-24T01:03:11		Emulate certain buil-in functions to work around driver bugs. This is implemented by adding a new compile option SH_EMULATE_BUILT_IN_FUNCTIONS. The emulated functions are names as webgl_originalName_emu so there will never be naming conflicts. At the moment only three functions are emulated: normalize, abs, sign. Also, the compile option will emulate all three. However, the mechanism to emulate only a selected subset is also imeplemented. It can be turned on easily. ANGLEBUG=196 TEST=with this option, the failed test with abs.frag passes.
