UG_DrawRoundFrame and UG_FillRoundFrame do rounded corners differently

[awocrf]

Hi It seems that UG_DrawRoundFrame is making nice rounded corners while UG_FillRoundFrame is making flat ones that look like you cut them with scissors (2x 45 degrees).

When I add the lines below to the end of UG_FillRoundFrame function it fixes that.

UG_DrawArc(x1+r, y1+r, r, 0x0C, c); UG_DrawArc(x2-r, y1+r, r, 0x03, c); UG_DrawArc(x1+r, y2-r, r, 0x30, c); UG_DrawArc(x2-r, y2-r, r, 0xC0, c);

I pulled them out of UG_DrawRoundFrame.

Maybe... ?

void UG_FillRoundFrame( UG_S16 x1, UG_S16 y1, UG_S16 x2, UG_S16 y2, UG_S16 r, UG_COLOR c )
{
   UG_S16  x,y,xd;

   if ( x2 < x1 )
     swap(x1,x2);
   if ( y2 < y1 )
     swap(y1,y2);

   if ( r<=0 ) return;

   xd = 3 - (r << 1);
   x = 0;
   y = r;

   UG_FillFrame(x1 + r, y1, x2 - r, y2, c);

   while ( x <= y )
   {
     if( y > 0 )
     {
        UG_DrawLine(x2 + x - r, y1 - y + r, x2+ x - r, y + y2 - r, c);
        UG_DrawLine(x1 - x + r, y1 - y + r, x1- x + r, y + y2 - r, c);
     }
     if( x > 0 )
     {
        UG_DrawLine(x1 - y + r, y1 - x + r, x1 - y + r, x + y2 - r, c);
        UG_DrawLine(x2 + y - r, y1 - x + r, x2 + y - r, x + y2 - r, c);
     }
     if ( xd < 0 )
     {
        xd += (x << 2) + 6;
     }
     else
     {
        xd += ((x - y) << 2) + 10;
        y--;
     }
     x++;
   }
  UG_DrawRoundFrame(x1, y1, x2, y2, r, c );
}

This one works too but I don't know if it's faster or not

[deividAlfa]

It should perform pretty much the same. Please note I'm not the author of uGUI neither I'm developing this fork anymore. My main contribution was adding a new font structure and UTF-8 support. If this works for you consider making a pull request. Thanks!

[awocrf]

Yeah, this works for me but I have no idea how to create a pull request with this patch since I've never used this feature before
