[RFE] Icon alpha on Linux

[Elviz]

• Ubuntu 10.04 (lucid)
• LWJGL 2.4.2

Even when the byte buffers passed to Display.setIcon contain proper alpha data, the displayed icon(s) will only have on/off transparency. This is especially visible when using the Alt+Tab window switcher. I noticed that the icons of other applications (i.e., non-LWJGL ones) don't have this problem, so apparently there's some level of support for 8-bit transparency that LWJGL doesn't currently make use of.

A similar limitation in the Windows port was removed some time ago (r3227).

Another thing related to program icon -- when setting a custom icon there is often a delay before the icon is changed from the default LWJGL one. I guess this is because the system is busy loading the rest of the program and processing; although Display.setIcon() is the first thing I call after Display.setDisplayMode(), sometimes the default LWJGL icon is visible for a second or two.

Would it be possible to set the icon before opening the display?

someone needed the feature so they provided a patch for windows.

I'm sure if someone provides a patch for this feature it'd be added.
