fix blend_state in test-001
+ test-002, testing alignment issues of getbits/putbits of bitmap and output surfaces
test-001: add smoothing test for vdpOutputSurfaceRenderBitmapSurface
rename variable in softVdpOutputSurfacePutBitsNative for consistency
add alignment handling to softVdpOutputSurface{Get,Put}BitsNative
fix: one should change GL_PACK_ALIGNMENT when reads data from texture

fixed first part of test-002
fix error in test-002
