Retrieve 2 1D convolution parameter "kernels" as pixel data

Variables	Description
target	The separable filter to be retrieved. Must be GL_SEPARABLE_2D .
format	Format of the output images. Must be one of GL_RED , GL_GREEN , GL_BLUE , GL_ALPHA , GL_RGB , GL_BGR GL_RGBA , GL_BGRA , GL_LUMINANCE , or GL_LUMINANCE_ALPHA .
type	Data type of components in the output images. Symbolic constants GL_UNSIGNED_BYTE , GL_BYTE , GL_BITMAP , GL_UNSIGNED_SHORT , GL_SHORT , GL_UNSIGNED_INT , GL_INT , GL_FLOAT , GL_UNSIGNED_BYTE_3_3_2 , GL_UNSIGNED_BYTE_2_3_3_REV , GL_UNSIGNED_SHORT_5_6_5 , GL_UNSIGNED_SHORT_5_6_5_REV , GL_UNSIGNED_SHORT_4_4_4_4 , GL_UNSIGNED_SHORT_4_4_4_4_REV , GL_UNSIGNED_SHORT_5_5_5_1 , GL_UNSIGNED_SHORT_1_5_5_5_REV , GL_UNSIGNED_INT_8_8_8_8 , GL_UNSIGNED_INT_8_8_8_8_REV , GL_UNSIGNED_INT_10_10_10_2 , and GL_UNSIGNED_INT_2_10_10_10_REV are accepted.
row	Pointer to storage for the row filter image.
column	Pointer to storage for the column filter image.
span	Pointer to storage for the span filter image (currently unused).
