gfx_render_text uses floats for layout, so the parts_text layout should
use floats to match.
This fixes an issue with off-center text in the English version of Rance
01.
This adds a new parameter `blend` to `gfx_draw_glyph()`. When `blend` is
true, the function performs normal alpha blending (same as
`gfx_draw_glyph_to_pmap()`).
If `blend` is false, the resulting pixel color will be the text color
and the alpha value will be copied from the glyph texture. However, if
the alpha value is less than 0.01, the pixel will not be written.
If you are drawing on a transparent texture (which will later be blended
into another texture), `blend` should be false. If you are drawing on top
of an image, `blend` should be true.
`gfx_draw_glyph()` used to fill transparent pixels with text color, but
this step is no longer needed and has been removed.
Don't allocate massive textures for each text object. Instead, allocate
a texture for each character and then compose them onto an appropriately
sized texture.
Fixes a performance issue in Rance 01.
Add a scene_print function which prints a textual representation of the
current scene. This works by attaching a `debug_print` function to each
entity in the scene. This function is implemented for SACT2 and
GUIEngine entities. A default implementation will be used of none is
provided.
This can be accessed from the debugger via the `scene` command (although
the output is typically too much to view in a terminal; it's better to
run `scene_print` somewhere and redirect stdout to a file).
