FS#116 - assertion fails when using "filter all" with small-palette images

When using “filter all VALUE” with an image_map using a 4-bit (16-color) paletted bmp image, debug builds of POV-Ray fail with an assertion.

According to code analysis, other paletted image formats with <256 palette entries are also likely to be affected; similar assertion fails can be expected when using the “filter INDEX, VALUE” feature on such files with an index exceeding the palette size. “transmit” shows the same flaws.

Parser code for “filter|transmit all VALUE” and “filter|transmit INDEX, VALUE” always presumed a 256-color palette.

Fixed with change #4992.
