draw_textn Improvement

Introduction

This patch should give a small speed boost to the function draw_textn.

Description of Patch

Since draw_textn is a heavily called function, even minor changes can have a big impact over time. This patch merely creates a temporary variable in place of constantly recalculating the same equation multiple times in a loop.

Installation of Patch

cd <motion dir>
gunzip draw_textn-0.01.patch.gz
patch -p1 < draw_textn-0.01.patch
make clean
make
make install (as root if needed)

Discussion and Comments

Andrew great ! I think that the patch could be improved a bit more to avoid some CPU cycles The way i did is adding a new temp variable that include the x value in the for over x.

for (x=0; x<6; x++) {
int tempvar_x = tempvar +x;

...

image[tempvar_x+1+(y+starty)*width]=0;
