[cycheng]

Document the following 1x2_2x2 matmul functions:

float2 img_matmul_float_acc_1x2_2x2(float2 a, __local float4 * b, float2 acc)
float2 img_matmul_half2_acc_1x2_2x2f(half4 a, __local half8 * b, float2 acc)
half2 img_matmul_half2_acc_1x2_2x2h(half4 a, __local half8 * b, half2 acc)
uint2 img_matmul_uchar4_acc_1x2_2x2(uchar8 a, __local uchar16 * b, uint2 acc);
int2 img_matmul_char4_acc_1x2_2x2(char8 a, __local char16 * b, int2 acc);
int2 img_matmul_char4_acc_1x2_2x2(uchar8 a, __local char16 * b, int2 acc);
int2 img_matmul_char4_acc_1x2_2x2(char8 a, __local uchar16 * b, int2 acc);
uint2 img_matmul_uchar4_acc_1x2_2x2_sat(uchar8 a, __local uchar16 * b, uint2 acc);
int2 img_matmul_char4_acc_1x2_2x2_sat(char8 a, __local char16 * b, int2 acc);
int2 img_matmul_char4_acc_1x2_2x2_sat(char8 a, __local uchar16 * b, int2 acc);
int2 img_matmul_char4_acc_1x2_2x2_sat(uchar8 a, __local char16 * b, int2 acc);

Editorial note: I suggest checking the rendered HTML to ensure that the text is wrapping the way you would like it to wrap, especially in some of the examples showing how the matmul operation takes place.

Confirming: do you want this extension to have the same version number even though it is adding functionality?

[cycheng]

Thank you, bashbaug! Increasing the version seems better, should I increment the 'Minor' or 'Patch' version?

Thank you! Confirmed again with two different renderers.

Discussed in the December 10th teleconference. @paulfradgley will give this a final review and if everything looks good we're OK to merge.
