Potential fix for https://github.com/echoix/grass/security/code-scanning/7126
To address the risk of overflow, make sure the multiplication happens in double-precision, not a smaller data type. The most reliable fix is to cast either
D_Cap->zorD_spec->yscaleto double before performing the multiplication. This ensures the multiplication itself is evaluated in double-precision and no intermediate overflow can occur in smaller types. The required change is on line 69 in raster3d/r3.showdspf/draw_cappolys_ogl.c:Change
