RCBasic v4.3 fixes a few bugs and finally adds android support.

The new features/improvements are:

• Android support (NOTE: Android builds can currently only be done from the linux version)
• Added the option to use a separate mesh as a collision mesh to Serenity3D
• Added the ability to used a detached collision object for Sprites in Nirvana2D

The fixes are:

• Fixed Serenity3D API not getting the Actor index
• Fixed the slow down that would happen when "Show Grid" is selected in Nirvana2D
• Fixed GetMaterialConstant() and SetMaterialConstant() not returning or setting the material values

There are a number of other under the hood features that were changed or improved but they were mostly structural and won't effect developers.
