[PD] Patch rendering theming: color scheme and text wheight

[Alessio Degani]

Hi Johnathan, and list.

Thank you for your reply.

I've checked the code for some of the sys_vgui calls by comparing 
vanilla ones with the one of extended.
It seems that the code is the same.

For example, the g_numberbox.c use sys_vgui call to draw the rectangle 
and text, but on vanilla and extended is the very same code:

sys_vgui(
     ".x%lx.c create line %d %d %d %d %d %d -fill #%6.6x -tags %lxBASE2\n",
     canvas, xpos, ypos,
     xpos + half, ypos + half,
     xpos, ypos + x->x_gui.x_h,
     x->x_gui.x_fcol, x);
sys_vgui(".x%lx.c create text %d %d -text {%s} -anchor w \
     -font {{%s} -%d %s} -fill #%6.6x -tags [list %lxLABEL label text]\n",
     canvas, xpos+x->x_gui.x_ldx, ypos+x->x_gui.x_ldy,
     strcmp(x->x_gui.x_lab->s_name, "empty")?x->x_gui.x_lab->s_name:"",
     x->x_gui.x_font, x->x_gui.x_fontsize, sys_fontweight,
     x->x_gui.x_lcol, x);

I think that the -fill parameter is the one responsible of the color, 
but is the same both for vanilla and extended.

I've also checked the code in s_intern.c (the place where sys_vgui is 
defined), and there are no difference between vanilla and extended.

Any idea?

Thank you

Alessio
