new r1gl just killed particuls on my ATI card

[Lemonzest]

Hi, as title, just updated my build to latest of both r1q2 and r1gl and now particles are the cross sprite like when gl_ext_pointparamiters is not available, was ok in last build of both.

edit: going back to previous r1gl build and keeping new r1q2 build fixes it, so looks like bug is in r1gl.

I gather sprites are now used to speed things up?

try set gl_ext_point_sprite 1

May as well point out that with this setting railtrails are being drawn a second time just after vanishing (on full, fade out, on full for a split second).
